- * - SOFT HYPHEN (U+00AD) has a column width of 1.
- *
- * - Other format characters (general category code Cf in the Unicode
- * database) and ZERO WIDTH SPACE (U+200B) have a column width of 0.
- *
- * - Hangul Jamo medial vowels and final consonants (U+1160-U+11FF)
- * have a column width of 0.
- *
- * - Spacing characters in the East Asian Wide (W) or East Asian
- * Full-width (F) category as defined in Unicode Technical
- * Report #11 have a column width of 2.
