Unusable codes can be generated

[saoir]

This issue occurred with a particular code from the online generator but I'm posting it here because it could potentially affect any code.

I used these options:

English Switch
Fire-Red
Create 31IV Egg from Nothing

I generated a bunch of eggs without issue but when attempting to generate a bellsprout (species 69), I was given this code for Box 1:

Box 1: B C U n t G . o [BCUntG.o]

I tried entering it a few times and it wouldn't save the name. I think the game is using a language filter and preventing the box name from being used (because of letters 2 through 5).

I don't have any particular suggestions on how to handle the issue, I just wanted to make you (and anyone creating codes) aware of it.

(tbh I also thought the issue was kinda funny and wanted to share it)
