TUI renders percent-encoded bare paths instead of decoded Unicode in local file links #16622
Description
Bug
When a model emits Markdown links with bare (non-file://) path destinations containing percent-encoded characters (e.g. %C3%B6 for ö, %20 for spaces), the TUI transcript renderer displays the raw encoded text instead of the decoded file-system path.
Current behavior:
/Volumes/Archiv%201/Bilder/Pers%C3%B6nliches/Kleidung/
Expected behavior:
/Volumes/Archiv 1/Bilder/Persönliches/Kleidung/
Root cause
In codex-rs/tui/src/markdown_render.rs, function parse_local_link_target():
- The
file://URL code path correctly decodes viaUrl::to_file_path() - But bare paths (starting with
/,~/,./) are passed throughexpand_local_link_path()without percent-decoding
Fix
Add urlencoding::decode() before expand_local_link_path() (line ~792):
// Before:
Some((expand_local_link_path(path_text), location_suffix))
// After:
let decoded = urlencoding::decode(path_text).unwrap_or(std::borrow::Cow::Borrowed(path_text));
Some((expand_local_link_path(&decoded), location_suffix))Also add urlencoding = { workspace = true } to codex-rs/tui/Cargo.toml (already in workspace deps).
