OK, found this:
So, I tried turning off tittle prettify
, but then it rejects all my CJK titles with all-caps English words. If I change those all-caps English words into mix-caps, then it is accepted.
The rejection says: Title seems unclear, is it a complete sentence?
If I change even one letter in the all-caps word into lower-case, then suddenly it seems to be a complete sentence to the system.
SUGGESTION: When a title contains more non-English letters than English letters, it is most likely a foreign language. In that case, you really should be by-passing most of the English-based rules.
