in case you entered keywords that should highlighted in chat containing umlauts or other special characters, then backup/export your BTTV settings, the umlauts and special characters are saved as “�”.
In my case I want to highlight the German word “fußball” (football). The exported json (.backup) file has the value “fu�ball”. This is the case with German umlauts like ä, ü, ö as well.
It seem thing with nickname case. I try to open my backupfile by notepad. It show some error code like “bttv_nicknames”:{“imapt”:“I-a-8H”,“maris”:"!2#4*",“teanskylighs”: I-a5",“cool_s”:“A!eL”}. How to convert them to the German word?
You can’t really convert it back, but you should be able to edit it and save the file properly. I think the issue is due to the encoding settings used whilst saving, not sure if it’s using UTF-8, but I reckon that’d be the best one, and the fact that it converts characters that are outside the US keyboard makes me think it’s probably using ANSI.
