Closes #118 This also sets ``*`` positional/keyword argument enforcement for all of the new proposed API functions Characters with the Unicode Default_Ignorable_Code_Point property should be rendered as zero-width per Unicode Standard. This fixes U+3164 HANGUL FILLER, U+FFA0 HALFWIDTH HANGUL FILLER, and ~3700 reserved codepoints that were incorrectly returning non-zero width. Two exceptions are preserved: - U+00AD SOFT HYPHEN: remains width 1 (ISO-8859-1 compatibility) - U+115F HANGUL CHOSEONG FILLER: remains width 2 (Hangul jamo composition)
