[BUG] Certain characters get weird in commit messages.

[hrs-o]

Hi, I am using the Japanese.
I noticed that when I do a commit with fork, certain characters don't get as expected.
This is due to the Unicode combining character.

Details are described below, but the problem is "ハ" and "゛" are not "バ" as a byte string.
Therefore, the search does not match.

I committed on fork and terminal.

    バナー commit by terminal

I did git log at terminal and checked the character code of "バナー".

• fork

U+E3838F
U+E38299
U+E3838A
U+E383BC

• terminal

U+E38390
U+E3838A
U+E383BC

U+E3838F is "ハ" of Japanese katakana.
U+E38299 is "゛" of Japanise voiced sound (dakuon).

It seems that it duplicated with #444, so it closes.
