I can't think of a many such titles though. Maybe "UX" for a general discussion about user experience?
Edit: oups, I had read "English speaking" rather than "non-English" ; with ideograms, it is actually quite obvious, thanks for the remark!
In Chinese and Korean, a single unicode codepoint encodes a full syllable, so two codepoints can be a word or even a short sentence.
So, depending on your writing skills, it can be a lot. You could use the begining of a poem or a sentence, which would be understood by the readers. For instance if you say “温古" it refers to a Confucius quote meaning "warming the past to learn the new".
But more interestingly, I think the restrictive and top-bottom rules edicted in Discourse and Stack Overflow may be some kind of mistake, or ultimately lead to dead ends. It goes against the natural grain of all things internet. It is AOLish, if you allow the neologism.
The leading successes of internet, i.e. Wikipedia, Google search, have had their massive growth and exitement when they were in extensively all-accepting mode. Reddit and 4chan are also in this kind of mode.
It seems probable to me that the next break-through will be again lifting artificial limitations there is on e.g. Stack Overflow.
