Incorrect DayOfWeek Translation for Chinese Variations

[jfong99]

Similar to the issue raised in #97, the fix given only works if the user's device is in zh-CH. However, when a user is using a variation of Chinese like zh-TW or zh-HK the incorrect DayOfWeek translation for SHORT reappears, displaying "星" instead of "一、二、三...".

I'm open to a PR for this.
