We have a request to improve the font rendering in the pull request view, specifically regarding the display of full-width characters.

In the code view, a monospaced font is used where full-width characters occupy exactly twice the width of half-width characters. This makes the code alignment, especially in languages such as Japanese, consistent and readable.

However, in the pull request overview, a different font is used where full-width characters do not necessarily take up exactly twice the width of half-width characters. This results in misaligned code or text when full-width characters are mixed with half-width ones.
