(I realize that this is probably not something that the JLU mods have control over, but maybe it can be submitted to the general SE people if enough people agree with it)
The current minimum length for a question title is 15 characters. This would probably be reasonable if weren't using a lot of Japanese characters. This minimum length was problematic for me when I created at least two questions.
Desired/Original title on left (number of characters) → Final title
いえ vs. うち (9 characters) → Difference between いえ and うち
すぎ vs. すぎる (10 characters) → Using すぎ vs. すぎる
Personally, I think the original titles were fine. But I could not submit them since they were under 15 characters. If I would've written the Japanese in romaji, the second title would've been 15 characters even.
Because we are JLU and our titles usually contain Japanese, I think it would be reasonable to ask for the minimum length to be reduced since one could argue that Japanese can express more in fewer characters.
