Pull request overview
Adds iOS-side decoding for numeric HTML character references so HTML persisted from Android (which emits non‑ASCII as &#NNNN; / &#xHHHH;) renders as proper Unicode text when loaded into the iOS editor.
Changes:
- Decode decimal numeric character references of the form
&#NNNN;. - Decode hexadecimal numeric character references of the form
&#xHHHH;into UTF‑16 (including surrogate pairs for code points >0xFFFF).
