What
The text Claude Code writes into your terminal title bar is normalized to NFC before control code points are turned into spaces, enclosing-marker and circle glyphs are collapsed, long titles are truncated with an ellipsis, and :// is rewritten with a lookalike slash so a title cannot read as a real URL.
Details
Normalization runs first, so composed and decomposed forms of the same character are sanitized identically.
Evidence
normalize("NFC")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
