It's still okay to use them for your own text characters ("É", "¿", "♪", "♥", etc), just don't use those tiles in any map names. Tiles $CE and $CF are completely unused. You can also replace some existing characters: the semicolon ";", \[brackets], and “curly quotes” are only used for nicknames (see [data/text/name_input_chars.asm](../blob/master/data/text/name_input_chars.asm) and [data/text/mail_input_chars.asm](../blob/master/data/text/mail_input_chars.asm)), and "`<COLON>`", "`<BOLD_V>`", and "`<BOLD_S>`" wouldn't be missed if replaced by plain ":", "V", and "S". |
