描述
Description
A <Text> whose content contains the 🫨 emoji (U+1FAE8, Unicode 15.0) renders with the last emoji of the line partially or fully cut off at specific text widths on Android. iOS is unaffected.
What we verified:
- The 🫨 emoji is the trigger. We compared emoji suffixes of the same length (14 emoji) at the same text widths: a sequence containing 🫨 (
😂🙁☠️😠🤔🥶🫨😺👏🏻🙁😂🥶😂😠) clips; 14 keycap sequences (1️⃣…🔟) and 14 single-codepoint emoji (🔴🟠🟡…) do not. Replacing 🫨 with another emoji in the failing sequence stops the clipping. - Width-dependent. Only strings whose width lands near the line-wrap boundary clip; adding or removing one letter makes the bug appear or disappear.
- Device-dependent. Different devices clip at different string lengths (verified on Huawei P30 Pro VOG-L29 / Android 10 and a Samsung device; exact failing rows differ).
- Version- and architecture-independent. Reproduces identically on RN 0.73 (old architecture) and RN 0.83.6 (new architecture) in the same app.
- Not markdown/library related. Reproduces with a bare
<Text>.
Steps to reproduce
- Clone https://github.com/mariia-korzun/EmojiEndClipRepro — a fresh community template where only
App.tsxchanged. It renders a sweep of 1–40 letters + a 14-emoji suffix in several layouts (chat bubble, fixed width, full width) plus a no-emoji control section, with the three suffix constants for comparison. yarn install && yarn androidon an affected device.- Scroll the EMOJI section: several rows show the last emoji clipped or invisible. The CONTROL section never clips. Replace 🫨 in the suffix — no row clips.
Expected: the trailing emoji is fully visible (as on iOS, and as with sequences without 🫨). So 😠 in the end should be visible
Actual: at specific widths the last emoji of the line is cut off. Screenshot attached.
With colors and numbers emojis all fine. Issue just when 🫨 in list. So 😠 in the end not visible

调研方向
从必需的 EmojiEndClipRepro repository 及其 App.tsx 开始,然后在受影响的 Android 设备上运行 yarn install && yarn android。比较 EMOJI 和 CONTROL sections,以及包含 🫨 的 suffixes;完成的标准是:末尾的 emoji 在之前失败的宽度下仍保持完全可见,且不会导致其他 layouts 或 emoji sequences 出现回归。
