Add UTF-8 support to " and ' delimited strings/characters

Very low priority (and probably a bit messy), but it would be kinda nice to add UTF-8 support to tables, print commands and table files in a future version of Asar.

I remember working on some German patchs in the past where umlauts like ÄÖÜ caused problems and I had to write these characters as hex values instead. My VWF patch would certainly greatly benefit from this feature, but I think it would be useful to international users in general. Code compatibility should still be granted, since code uses only ASCII commands. Some strings using ANSI characters >= 128 might break from a transition, but there should only be few cases like that and they wouldn't break too horribly - only some characters would get replaced by garbage characters or disappear.

This would be useful for my Core Dump patch, which uses UTF-8 to store text in the ROM.

This has been completed in the asar2 branch. It will not be backported. Closing.
