So address it. Unicode report TR18 says (for Level 1 support):
RL1.4 Simple Word Boundaries
To meet this requirement, an implementation shall extend the word
boundary mechanism so that:
1.
The class of <word_character> includes all the Alphabetic values from the
Unicode character database, from UnicodeData.txt [UData]. See also Annex C:
Compatibility Properties.
2.
Non-spacing marks are never divided from their base characters, and
otherwise ignored in locating boundaries.
Level 2 provides more general support for word boundaries between
arbitrary Unicode characters which may override this behavior.
Level 1 support should certainly be met.
