As long as wider letters have widths that is integral of the narrowest letters (ASCII?), "use N columns, padding with '.' if needed" has a reasonable solution, no? "[1]A[2]" occupies 2+1+2 columns, so trunc that is given only 3 (or 4) columns can drop the last "[2]" and fit "[1]A" in the given columns with padding. > I'll at least work on the doc clarification regarding the column width, > column position and wide char (2-col) issue, and hopefully a few failing > tests for the combing code point and the wide char fitment issue. Thanks, that would give us a very good starting point.
