I haven't analyzed the proposed mapping in detail, but note that the
col() function counts memory _bytes_, i.e. always one for a hard tab
(which occupies between one and eight screen columns, or more with
nonstandard values of 'tabstop'), but OTOH in UTF-8 three for CJK
characters in the BMP (below U+FFFF) and four for CJK characters above
U+FFFF, though (as CJK "wide" glyphs) they each occupy only two screen
cells. To count screen columns you need the virtcol() function, which
you used elsewhere in the same mapping.
Best regards,
Tony.
