Some terminals have a bug where control codes they do not recognise show up as stray characters on screen.\n\nClaude Code now takes the terminal type into account when deciding whether title setting is supported. For terminals known to have this bug, it treats the question as not yet settled rather than going ahead, and records that the terminal prints unknown codes.\n\n**Why**\n\nThis should stop stray characters from appearing in the affected terminals.\n\n- Area: Terminal UI\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
