translate them to bare ISO-8859-1 at print time Only alters chars with codes > 0x9f, so graphics/symbols in the 0x7f-0x9f range and color and control codes < 0x20 are preserved The routine assumes that any char code > 0x9f is the first byte of a two-byte UTF-8 symbol. Note that due to Minetest's busted formspecs, it's not possible to actually type-in or copy-paste proper UTF strings to take advantage of this mode, so it's only useful if the strings are generated by or imported in from something else (e.g. a URL or something, or a LuaC program that generates strings)
