Cases such as similarity('', '') produced a NaN result due to computing 0/0. Per discussion, make it return zero instead. This appears to be the basic cause of bug #7867 from Michele Baravalle, although it remains unclear why her installation doesn't think Cyrillic letters are letters. Back-patch to all active branches. |
