Reminder pushes (medication-due, mood, briefing, cycle) carried the colour-coded phase markers the Telegram channel uses, which leaked onto the iOS lock screen and other push channels as decorative bubbles. Strip emoji in the APNs, Web Push and ntfy senders for every event except SYSTEM_ALERT, so routine reminders render as plain text while system / failure alerts keep their severity glyphs. Telegram is unchanged — emoji stay idiomatic there.

/**
|
|
* Strip decorative emoji from push notification content.
|
|
*
|
|
* Operator + iOS contract (2026-06): routine reminder pushes
|
|
* (medication-due, mood-nudge, daily-briefing, cycle reminders) must be
|
|
* plain text — no emoji, no decorative bubbles. iOS renders the APNs
|
|
* `title`/`body` verbatim, so the colour-coded phase markers (🟢🟡🟠🔴) the
|
|
* reminder strings carry for the Telegram channel leak onto the lock
|
|
* screen. Emoji stay acceptable only for system / failure alerts
|
|
* (`SYSTEM_ALERT`), where they flag severity.
|
|
*
|
|
* The push senders (APNs, Web Push, ntfy) run reminder content through
|
|
* this; Telegram keeps the emoji (idiomatic there, and its inline keyboard
|
|
* relies on glyph-labelled action buttons). `shouldStripEmoji` keeps the
|
|
* SYSTEM_ALERT carve-out in one place.
|
|
*
|
|
* The range set targets the actual emoji blocks (supplementary
|
|
* pictographs, misc symbols, dingbats, geometric/arrow emoji, regional
|
|
* indicators, variation selectors, keycap) and deliberately spares the
|
|
* BMP punctuation that doubles as text — ™ © ® and the like — so a brand
|
|
* name in a medication title is not mangled.
