util.c: table_print_line: properly align texts involving CJK

For printf in C, width is counted as bytes rather than Unicode width. [1]

> If the precision is specified, no more than that many bytes are written.

[1] Section 7.21.6, N2176, final draft for ISO/IEC 9899:2017 (C18)

Thanks Andrew Gregory for suggesting a simpler approach.

Fixes FS#59229
