Hacker News

I run a couple similar sites:

FileFormat.Info[1] has a page per codepoint. It has been around awhile, so the UI isn't as whizzy, but it has all the data and works w/o JavaScript

UnicodeSearch[2] is an updated search UI that uses JavaScript and the excellent Tabulator grid widget.

There are actually a ton of similar sites with a page-per-codepoint. It is all fun to make one, until the bots come along and hammer every page.

Feature request: some context, history and/or example of popular usage.

Some symbols leave me with more questions than answers, like “LEFT HALF RUNNING MAN”[1].

I’d like to at least see that it’s a glyph part, that there are two in total, and what does the other half look like; right now the “right half running man” is not listed anywhere on that page, not even in the “related symbols” section.

Off topic, the running man symbol possibly comes from MouseText character set (the one in the Apple IIc[2]). It was one of many character sets included in the legacy computing block[3].

24h update after the Show HN — quick recap.

Based on the feedback here, I spent the last day tightening a few core things:

- Navigation / mobile: tapping a card now opens the symbol page directly; copy is a separate, larger button. The tiny expand target is gone.

- Search: alias + lightweight fuzzy matching is in (e.g. “section”, “angstrom”, “greater than”), plus a /codepoint/... fallback so pasting a literal character or U+XXXX always lands on a usable page, even outside the curated index.

- Missing glyphs: added a small “Font tips (if you see □)” section with system font notes and Noto suggestions.

- Content: HTML/CSS/JS guidance now recommends writing the literal character + UTF-8 by default; entities/codes are framed as legacy/reference only. Added Notes and improved Related (pairs, confusables, same block).

- Privacy: removed session recording; analytics are opt-in with a real reject-all (everything works fine with tracking off).

Direction going forward: fewer generic “how-to” instructions, more symbol-specific context — confusables, paired glyphs, rendering quirks, and references people actually look for.

Thanks again for the detailed feedback — it materially improved the project.

I find this page the cleanest: https://en.wikipedia.org/wiki/List_of_Unicode_characters. I can usually just do a Ctrl-F and find what I want.

Nice, but way too many abbreviated descriptions and no way to see the full name of a symbol without clicking on it. Needs a tooltip / title.

Or better, if 90% of all symbol names are abbreviated, your design simply doesn't work. This is especially apparent in the "arrows" section.

I’m looking at the currency block. Each box has a colored “drop shadow”. I spent a minute or so trying to figure out what the significance of the color is. Finally, I noticed that the color appears to cycle between cyan, magenta, and yellow. Is this a design element only, or do the colors actually have some meaning with respect to the symbol?

It doesn't fit my definition of "clean" at all, but that's a subjective word anyway. I do have some feedback (unrelated to being clean):

- The search field is arguably the most important element on the site. It might benefit from a magnifying glass icon and/or some visual distinctions that make it actually look like a text input for searching. It's thick border and shadow make it look like all the other boxes on the page that have thick borders and shadows!

- Speaking of the search field, it would be really nice if it supported fuzzy search. For example, I searched for "greater than" and got no results. I had to search for "greater-than" (with a dash) to find the math symbols (like ≥).

- The small font size of the symbols makes them really hard to see for old people like me who are pretending not to be old.

- Ditch the analytics and cookie consent nonsense. These are anti-developer!

Very clean design, congrats!

I’d love to see a section describing the glyph’s usage (I usual have to check Wikipedia for that) and which compose key sequence to use to type it. For instance on Linux (maybe other OSes too?) you can type <compose key> + e + = and get the euro sign.

Planning to add more symbol-specific notes (confusables, common pitfalls, rendering quirks). Curious what details people usually look for but can’t find.

Cool! Ideas: At least do an ensemble approach by queuering llms to explain what the symbols "are". It's so auto generated now. Link to wikipedia. https://en.wikipedia.org/wiki/Approximation#Typography

Developers need to understand context too, not see a static page of "macOS: Use Character Viewer (Control + Command + Space) and search by name, or copy/paste."

The related to symbols make little sense. For example: https://fontgenerator.design/symbol/acute-angle Does not link to all other "angle" pages, but does to Aktieselskab?

Clean ?

- Gratuitous, unnecessary cookies (and accompanying cookie consent dialog)

- cloudflare insights built into the pages

- non-zero counter in ublock origin

That's before we even get to the page source which contains, among other things:

  "text\":\"First, ensure you're using a modern browser. If problems persist, try refreshing the page or clearing your browser cache. Some older devices may have limited font support.\"}}

I haven't seen this on HN in a while so it is worth reposting:

You say "for every unicode symbol", which I guess is true if you search by code, but for anything that isn't in your curated set I'm unable to even find it if I paste the literal character or use the "official" name.

eg ℝ "Double-Struck Capital R" won't show up at all unless I search it as U+211D.

Sharing the UTF-8 Playground I built recently: https://utf8-playground.netlify.app/

Why do I get a spinning "waiting" on every page? That doesn't seem "clean" to me... That's supposed to be raw HTML with a search.

It's cluttered with how to put your HTML character in your HTML, while being supposedly focused for devs...

All that doesn't make sense to me.

It's odd that searching for "section" finds U+2E39 (Top Half Section Sign) but not U+00A7 (Section Sign).

The directions for input on on each operating system are all the same, use an app? On Windows there's a key sequence based on the codepoint integer. It should tell you exactly what to type. The Linux one is especially odd "Use the Character Map app or a Compose key sequence, then paste into your app" because if there's a compose key sequence you don't need to paste it.

Some constructive criticism:

Please don't display text directly on the grid background image. It makes it impossible to read the text easily. Currently, this is the case when you open the page for a specific symbol in the 'Usage & Context' section.

Could use a list of (free) fonts that support the corresponding glyph.

This is beautiful. Love the design. When I read the title I thought it was "one page per Unicode" so I click on the codes and hope a page will open with a giant Unicode where I can see about it in details.

Oh well! Still good.

When I click the "Click to copy" my UI reflex tells me to look for a "Copied!" or similar acknowledgement. But I don't see one, so there's uncertainty if it was copied safely to my invisible clipboard or not.

Please keep making this, it's good! What inspired you for the design? I like this style, and notice it around, but can't pinpoint.

Very nice.

I found it odd, that tapping on a square “highlights” it, by making it “pop,” but nothing else really happens.

It took me a bit to figure out that I need to actually select the arrow in the upper right corner, to get the page.

No disrespect but I would not call this "clean". The design is overwhelmingly cluttered and distracting. Especially given that each symbol is obscured by a black square with an arrow covering it. The symbols are themselves very small.

Maybe get rid of all the noise and just display the symbols in a nice grid without all the fluff or layers.

The styling/design doesn’t work with dark-mode extensions like Noir.

I really like this. I appreciate the many "copy" buttons that make it easy to grab various font values once I find a character. Good job!

Ohh, this is great! I actually was looking for something like this the other day. Thanks for sharing and nice work!

On mobile, the expand icon covers 1/4 of each character so it is hard to see what they are

My go-to site for Unicode symbols is graphemica.com. I like that you show very directly the different use cases, but miss different encodings and the ability to browse unicode sequentially.

How do I search for egyptian hieroglyphs? searching for "egyptian" neither for "hieroglyph" works

searching directly for 𓁤 also doesn't work

> Use an HTML entity, a decimal code, or a hex code.

Please no: just write the character. <, & and (in quoted attributes) " or ' are the only characters that need to be encoded; a few others have arguable benefit to being encoded (most notably NO-BREAK SPACE), but most Unicode characters should just be put in literally. The days when you couldn’t be confident of the file encoding are past: your HTML is being served as UTF-8 (or in the rare case it isn’t, you should fix that instead of avoiding non-ASCII in the source).

Same deal with CSS (" and \ are the only ones you need to escape) and JavaScript (" or ' or `, as appropriate).

URLs? Occasionally you may encounter a legacy system where you need to percent-encode it yourself (similarly around punycoding internationalised domain names), but you can almost always (and thus, in my opinion, should) just write it and leave anything that wants it to be ASCII to perform the percent-encoding itself.

Excel I can’t comment on, but I presume you can just write "≈" and UNICHAR should almost never be used.

I know the colors are a little ... intense, but I love it!

I'd like the hint to display the hidden parts of each box when hovered.

I don't need to be told on each one to "Click to Copy".

But nice concept.

Huh. Why can't it find "Angstrom" (U+212B)?

Quite useful, but that's far from "clean".

Very cool and helpful - I'll be using this a lot!

Interesting I discovered two new-to-me temperature symbols (℃ and ℉), but couldn't find the Alt-0176 ° generic degree sign that shows up on the MS Character Map app. I also found the There Exists symbol ∃ !! I'd been seeking for years; it was so useful since finding out about it in college logic courses... This will be even more useful when the Alt-code fields are all filled in! Thanks!
