Claude Code v2.1.20: Thai text output drops vowels and

Open 💬 9 comments Opened Jan 27, 2026 by top-jaileak

UPDATE: This is now a CRITICAL blocking issue.

Claude Code itself cannot type sara aa (า) when generating Thai responses, making it completely unusable for Thai language work.

Impact:

  • Users cannot type sara aa (า)
  • Claude Code cannot generate Thai text with sara aa (า)
  • Affects ALL Thai language workflows
  • No workaround except downgrade

This needs URGENT attention as v2.1.20 is currently broken for Thai users.
