it's the codepoint 0xb3 '³' (from iso-8859-2) which is no valid UTF-8 char,
possible fixes are: convert the tinrc into UTF-8 via

mv ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc /tmp/tinrc.bak &&
iconv -f iso-8859-1 -t utf-8 < /tmp/tinrc.bak > ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc

or fix the regexp and ommit the polish "bylo" part:
strip_was_regex=.\((?:[Ww]a[rs]):.*\)\s*$
