Not sure if this is out of scope or not, but when wide characters are present in column output mode they're still treated as one character wide, so column widths are wrong and text is misaligned. For example: ``` source dest ---------------------------------------- ----------------- Final Fantasy 7 (Famicom) Final Fantasy VII 最终幻想7 Final Fantasy VII Shenzhen Nanjing Technology Final Fantasy VII Final Fantasy VII (Famicom) Final Fantasy VII ``` There are various ways to check the printed width of a character, on Linux you can use wcwidth for example. If this is in scope, it'd be great to have it fixed.
