maybe (untested)

set stl+=%{substitute(getline('.'),\ '^.*\\(\\%'\ .\ virtcol('.')\ .\
'v.\\).*$',\ '\\1',\ '')}

with two single quotes (not just one double quote, and if you want two
double quotes they must be backslash-escaped) before the last closing
parenthesis.

or (maybe more readable)

let &stl .= '%{substitute(getline("."), ''^.*\(\%'' . virtcol(".") .
''v.\).*$'', ''\1'', "")}'

(here we must beware that to include a single quote in a single-quoted
string we must double it)

see
:help option-backslash
for the backslash-escaping in the operand of :set
:help 'statusline'
for %{ and }
:help expr-'
about the need for doubling ' inside a 'string'
and also
:help substitute()
:help getline()
:help pattern-atoms
:help :let-option
