'win.lines' contains the same content as the GtkTextBuffer, so to find @match_start, forward_chars_with_skipping() is called with skip_decomp=FALSE (the last parameter). So far so good. On the other hand, the content 'lines' (the needle split in lines) is casefolded and normalized for a case insensitive search. So, forward_chars_with_skipping(..., skip_decomp=TRUE) must be called only for the portion of text containing the needle. Since 'start_tmp' contains the location at the start of the match, we can simply begin at that location to find the end of the match. Unit tests are added. https://bugzilla.gnome.org/show_bug.cgi?id=758698
