SMS character counter

GSM-7 or UCS-2, parts, and characters left per part — the 3GPP TS 23.038 math carriers use, with the €-style characters that cost two symbols and the emoji that force UCS-2 counted honestly.
Message text

- No sending, no carrier API, no country rules — the segmentation math only. Some gateways re-encode or split differently; the page shows the 3GPP baseline.
- ZWJ emoji families count their raw code points — what phones actually send, not a “nice” emoji count.
