Different translation with ucs2/ucs4 with mixed capitals

[egli]

Using the en-us-brf.dis, eo-g1.ctb tables the string "defgDEFGdefg" translates to "DEFG..DEFG.'DEFG" when liblouis is compiled with ucs2. However when compiled with ucs4 it translates to "DEFG.D.E.F.G.'DEFG"

Input: 'defgDEFGdefg'
Expected: 'DEFG..DEFG.'DEFG' (length 16)
Received: 'DEFG.D.E.F.G.'DEFG' (length 18)
Diff: Expected '.' but received 'D' in index 5

This problem occurs in current master, i.e. before the ueb changes.

I can't reproduce with lou_translate on 3.0.0-alpha.
