Problem
Even if you select a variant kana font in Microsoft Office, it is not reflected.

1. Reproduction procedure
   Copy and paste variant kana from Wikipedia, etc. into Word.
   Select the copied and pasted kana and change it to the variant kana font.

2. Observed result
   Cannot be changed. The kana you tried to change remains in the original font.

3. Expected results
   The font changes to the variant kana font without any problems.

4. Additional information
   Noto Sans/Serif Japanese is also installed. This works without any problems.

Character data
𛀁 𛀙 𛀆, etc.

Currently, when there is a text that contains both variant kana and normal kana, if you specify Noto Serif Japanese as the overall font, the variant kana will be garbled. Even if this problem of not being able to specify it in the first place is solved, the problem of it being difficult to use at the same time as Serif Japanese will remain. For ease of use, I would like you to consider completely integrating it into Serif Japanese.
