# What

- Replace `title.len()` with `title.chars().count()` in the commit title
length check, so the limit is measured in Unicode characters instead of
UTF-8 bytes.
- Applied in two places that share the same logic:
  - `crates/git_ui/src/git_panel.rs` — Git panel's inline warning
  - `crates/git_ui/src/commit_modal.rs` — commit modal's inline warning

# Why

The commit title length check used str::len(), which returns UTF-8 byte
length rather than character count. As a result, titles containing
multi-byte characters (Japanese, Chinese, emoji, etc.) triggered the
warning far below the configured commit_title_max_length — around 24
characters instead of the default 72.
