QTBF: Fix issue with no splitting the words at "." (FULL STOP)

As of Unicode 5.1, some punctuation marks were mapped to MidLetter and MidNumLet
for better URL and abbreviations handling which caused "hi.there" to be treated
like if it were just a single word;
until we have the Unicode Text Segmentation tailoring mechanism, retain
the old behavior by remapping (some of) those characters back to their old values.
