Rather tricky. The problem is that we don't know how to get flex to works
with locale. Parser recognizes latin words ([a-zA-Z]), nonLatin ([\0200-\0377])
and mixed words ([a-zA-Z\0200-\0377]). Your case (balanceR) is the mixed word.
The right way is to have locale aware parser to properly recognize words.
We incline to refuse a flex.
