I think, something like this should work, not sure, if there is an
easier way:
len(split(matchstr(getline('.')[:col('.')],'.*'), '\zs'))
strdisplaywidth(matchstr(getline('.'), '^.*\%'.col('.').'c'))
strlen(substitute(getline('.')[:col('.')], '.', 'x','g'))

see the help at
:h strdisplaywidth()
:h strwidth()
:h strlen()
:h len()

:h |
:h l
:h h
