What happened?

CJK text without spaces is treated as one giant "word" during word wrap. After an English word + space, a long CJK sequence gets forced entirely to the next line, leaving a large blank area at the end of the current line.

Steps to reproduce

Run pi with output containing mixed English and CJK text, e.g. a long CJK sequence following an English word and a space. The CJK block wraps as a whole rather than breaking at character boundaries.

Expected behavior

CJK characters should break naturally at character/grapheme boundaries (like oversize Latin words do in breakLongWord), filling the current line before wrapping:
