Chinese characters are garbled, setting utf-8 is also garbled

[Nicholas Hsiang <xianghongai@xxxxxxxxx>]

Hi,

There are some problems here.

I have configured the character encoding in .gitconfig:

```yaml
[core]
  quotepath = false
[gui]
  encoding = utf-8
[i18n]
  commitencoding = utf-8
  logoutputencoding = utf-8
```

and Git Bash configed: Options > Text > Locale: zh_CN, Character set: UTF-8

However, when executing `git pull/reset/status`, Chinese characters
still appeared garbled.

```bash
Xiang@Xiang MINGW64 /c/me/front-end-note (master)
$ git reset --hard df576e2
HEAD is now at df576e2 doc: 琛ュ厖 ES5 缁ф壙
```

`git pull`:

```bash
Xiang@Xiang MINGW64 /c/me/front-end-note (master)
$ git pull
Updating df576e2..bd2894b

`git status`:

```bash
Xiang@Xiang MINGW64 /c/me/front-end-note (master)
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   浜夎涓庢帰绱?md

no changes added to commit (use "git add" and/or "git commit -a")
```

`git log` command is correct:

```bash
Xiang@Xiang MINGW64 /c/me/front-end-note (master)
$ git log --oneline -3
bd2894b (HEAD -> master, origin/master) i18n
73dceea 代码目录文件结构
89121aa 更新 NPM
```

My environment:

- windows 10 home chinese edition
- git version 2.28.0.windows.1

This problem did not appear in the previous version, and we look
forward to fixing it.

Thanks
