any name (even symbol or japanese) should work because what you type is not the actual file name. actual world filename is something like T_W_0A. all upper case and shorter than 8 letters. (program generates filename for you)

I tested 4 3DSs (2 original small 3DS, 2 big LL/XL 3DS.) and all of them worked.

months ago, I couldn't scan any new QR codes, I deleted useless files and resources and solved file creation problem. maybe you need to delete some files to make enough space. because one world uses 3 GRP files. (two for world data, one for light map)
