Generate a slug just like GitHub does for markdown headings. | 401 stars | JavaScript ## Bug Report: Emoji Variation Selectors Not Removed from Slugs - Author: [`@comanche`](https://github.com/comanche) - State: open - Created: 2025-10-16T21:02:41Z - Updated: 2025-10-17T06:45:53Z # Bug Report: Emoji Variation Selectors Not Removed from Slugs ## Description The `slug()` function does not fully remove emojis that contain Unicode variation selectors (U+FE00 to U+FE0F), leaving invisible characters in the generated slug. This creates broken anchor links. ## Expected Behavior Based on the test fixtures, emojis should be **completely removed** from slugs: - `"😄 unicode emoji"` → `"-unicode-emoji"` ✓ ## Actual Behavior Emojis composed with variation selectors leave the invisible variation selector character in the slug: - `"🗃️ File Cabinet"` → `"️-file-cabinet"` ✗ (contains invisible U+FE0F) ## Reproduction ```javascript const { slug } = require(&`#39`;github-slugger&`#39`;); // Simple emoji - works correctly console.log(slug(&`#39`;✅ Checkmark&`#39`;)); // Output: "-checkmark" ✓ // Emoji with variation selector - leaves invisible character console.log(slug(&`#39`;🗃️ File Cabinet&`#39`;)); // Output: "️-file-cabinet" ✗ (starts with invisible U+FE0F) // Inspect the bytes to see the problem const result = slug(&`#39`;🗃️ File Cabinet&`#39`;); console.log(&`#39`;Bytes:&`#39`;, Buffer.from(result).toString(&`#39`;hex&`#39`;)); // Output: "efb88f2d66696c652d636162696e6574" // ^^^^^^ = U+FE0F (variation selector - should not be here!) ``` ## Root Cause Some emojis are composed of multiple Unicode characters: 1. **Base emoji character** (e.g., `U+1F5C3` = 🗃) 2. **Variation Selector-16** (`U+FE0F`) - makes the emoji display in color Examples: - `🗃️` = `U+1F5C3` + `U+FE0F` (2 characters) - `1️⃣` = `U+0031` + `U+FE0F` + `U+20E3` (3 characters) - `✅` = `U+2705` (1 character) ✓ The current implementation removes the visible emoji character but leaves the invisible variation selector behind. ## Impact This breaks markdown anchor links in real-world usage: ```markdown ## 🗃️ File Management Link to section: [See File Management](`#-file-management`) ``` The link won&`#39`;t work because the slug contains an invisible character that doesn&`#39`;t match. ## Affected Emojis Common emojis with variation selectors include: - 🗃️ (File Cabinet) - ☑️ (Check Box) - ✔️ (Check Mark) - ⭐️ (Star) - ❤️ (Red Heart) - 1️⃣ 2️⃣ 3️⃣ (Keycap Numbers) - Many others with U+FE0F modifier ## Proposed Fix Strip variation selectors (U+FE00 through U+FE0F) after processing emojis: ```javascript function slug(value) { // ... existing slug generation code ... // Remove variation selectors that may remain after emoji removal result = result.replace(/[\uFE00-\uFE0F]/g, &`#39`;&`#39`;); return result; } ``` ## Workaround Users can post-process the slug output: ```javascript const { slug } = require(&`#39`;github-slugger&`#39`;); const result = slug(&`#39`;🗃️ File Cabinet&`#39`;).replace(/[\uFE00-\uFE0F]/g, &`#39`;&`#39`;); // Output: "-file-cabinet" ✓ ``` ## Environment - `github-slugger` version: 2.0.0 (latest) - Node.js version: v20+ - Platform: All platforms ## Additional Context Similar issues have been addressed in related libraries: - [emoji-regex `#45`](https://github.com/mathiasbynens/emoji-regex/issues/45) - variation selector handling - [emojibase `#1`](https://github.com/milesj/emojibase/issues/1) - variation selector capture This is becoming more common as modern emoji keyboards automatically add variation selectors for better rendering. --- **Would you like me to submit a pull request with the fix?** --- ### Timeline **`@wooorm`** commented · Oct 17, 2025 at 6:45am > this project follows how github works, so whether this is a bug depends on what github does; see the build scripts for more info; it can also be that GH now uses modern `unicode…[truncated]
Generate a slug just like GitHub does for markdown headings. | 400 stars | JavaScript ## Use custom unicode regex filter in place of emoji-regex - Author: [`@Flet`](https://github.com/Flet) - Association: OWNER - State: closed - Source branch: custom-regex-filter - Target branch: master - Mergeable: dirty - Commits: 1 - Additions: 3309 - Deletions: 8 - Changed files: 6 - Created: 2019-06-26T01:51:16Z - Updated: 2022-10-27T10:33:48Z - Closed: 2021-08-24T14:40:38Z This isn&`#39`;t quite ready, but I wanted to share it in case someone wants to help! :) OK, so `emoji-regex` does not cover a bunch of unicode characters that GitHub actually filters out, including the black heart and lozenge (`#22`) So, digging around, I found `regenerate` which can be used to create a unicode regex string and [unicode-12.1.0](https://github.com/mathiasbynens/unicode-12.1.0) which has all of the unicode character blocks nicely defined. In fact, `emoji-regex` uses `unicode-12.1.0` to build its regex. This PR removes `emoji-regex` as a dependency and instead uses a script to build a custom regex from the unicode blocks incoded in `emoji-regex` plus additional blocks that GitHub filters out when it creates slugs. So, I&`#39`;ve been going through each unicode block (like [this one](https://unicode-table.com/en/#miscellaneous-symbols-and-pictographs) and validating that GitHub filters it by pasting a same of characters into a markdown header in a GitHub Gist [like this](https://gist.github.com/Flet/02a240f8177b35eb88c23c4fb9b9f799). I have a few covered but not all (its a tedious task 😢). I&`#39`;m guessing it will end up being a big range (or a few ranges) that GH filters from their slugs. If anyone has a better idea on how to do this, please feel free to help! :) --- ### Timeline **Dan Flettre** pushed commit `25cdb15`: Use custom unicode regex filter in place of emoji-regex · Jun 26, 2019 at 1:44am **`@wooorm`** commented · Jun 26, 2019 at 7:04am > I maintain a project of GitHub emoji, at https://github.com/wooorm/gemoji. That pulls stuff in from GitHub Gemoji itself. Some things: > > - They’re about to release a big new batch of gemoji, but that could be a while > - Previously, their shortcodes sometimes mapped to values that are not seen as emoji (whole thing with font variant selectors and unicode), that’s likely to change in the coming release > > Regenerate makes sense so we can add only the values that GitHub supports. > *But*, how do we know which values GH strips? Where’s the code they’re using?

Update the evaluation link anchor.
