Description Pierre Ossman cendio 2025-02-20 11:20:27 CET 
Keyboard layouts that have symbols outside of Unicode's 16-bit basic multilingual plane (BMP) do not currently work in ThinLinc on Windows and macOS.

This is because both of them use UTF-16, and hence need to have a surrogate pair to represent these symbols. A quick test shows that things work fine if we merge these to a normal 32-bit codepoint and send the corresponding keysym.

Affected layouts are those for very recent scripts, so likely not too common:

 * Adlam
 * Hmong
 * Osage
 * Hanifi Rohingya
 * Wancho

Discovered during bug 5272.
