"document title is too short" for Chinese

[hemind]

Now the number of Chinese characters of document title is limited to equal to or more than 3. But actually Chinese mountain names with 2 characters is very common, and 1 character name can also be meaningful for a route name.

So I suggest to set the limit of number of Chinese characters to 1.

I will close this since this is an ui related issue.
