Problems with Chinese, Japanese or Cyrillic encoding are quite common. Some users were able to open text files with Chinese characters without any problems, but they seem to have been corrupted.
Some changes had to be made to prevent the text from displaying inconsistently. Here are the steps to fix the corrupted Chinese characters.
There are several ways to fix this problem. First, we recommend that you change the encoding to UTF-8 instead of the default. An alternative option is to copy the content and put it into an HTML file. After that, open the file in a browser and change the encoding to get the correct version of the text.

Change the text format
You can change the text format of your response by clicking the File tab. Click Settings, then click Mail. Find the “Write in this message format” list. From the list, select Plain Text or HTML, then click OK.

Disable Show Markup by pressing Ctrl, Shift, and 8 at the same time.
