 ### Fixes
 
 - Onboarding/CLI: restore terminal state without resuming paused `stdin`, so onboarding exits cleanly after choosing Web UI and the installer returns instead of appearing stuck.
+- macOS Voice Wake: fix a crash in trigger trimming for CJK/Unicode transcripts by matching and slicing on original-string ranges instead of transformed-string indices. (#11052) Thanks @Flash-LHR.
