Mery and TeraPad are text editors.

When using input method (IM) to input Japanese characters, undetermined strings
are not displayed.
Candidates are displayed.
Conversions are done successfully.
It occurs with Wine 7.13 or later.

Undetermined strings are displayed inline with Wine 7.12 or earlier, after
several conversion after starting the application.

note:
  Right after starting the application, undetermined string is not displayed
with all tested version of Wine, but it should be another bug.

Given the range, most likely related to imm32/win32u code shifts that took
place then (two significant commit series: one starting at
d9fc5b3f967f1c5126278565beb6b967f9d6d80a (5 commits), second at
3e8a4b671dca2d22596c43157e2ae80fcfe18737 (8 commits); a few more commits beside
- all from the same author).

I can confirm. `git bisect` says:

f6ddd4ca86672fe2739ea7d17015112bce677e21 is the first bad commit

Is it still a problem in current git? imm32 code had a lot of changes.
