I’m having an issue with searching in a folder that starts with 一. Query path:"一Templates/" returns no results, while same folder contains notes. Renaming to Templates fixes it.
I use 一 to sort templates folder to bottom - it’s cleaner than using zTemplates.
Is there a known limitation with non-Latin characters in path queries?
For the same reasons, I’m using (mainly) “_” and “-” from time to time, and it is working. I tried your “一”, and yes, the folder/note is not showing up in the search results.
This is not an answer to your question 
but just to let you know.

But these put a folder at the very top, not bottom 
I was not careful when reading and missed the “to bottom” part. I’m sorry. Usually, I put that kind of stuff at the top, so that’s why I was so confident replying 
I didn’t even know that “一” was sorted to the bottom! So I learn something new.
I guess then I couldn’t help 
Cheers, Marko
I forgot that I had excluded the folder in question in Files and links settings. Silly me.
