function markupSWpartsOfString returns non-cropped results, because the t3lib_cs::strlen('utf-8',...) fails on non-unicode strings, returning. It sure may be my failure to let non-utf-8 strings into index table, but i can't control it thoroughly now. Our website is served as latin1.

iconv_strlen(): Detected an illegal character in input string in
t3lib/class.t3lib_cs.php on line 1428

changing t3lib_cs::strlen('utf-8',...) to t3lib_cs::utf8_strlen(...) in markupSWpartsOfString resolved the issue.
