If the egg needs to be able to correctly handle arbitrary characters, UTF-8 is the appropriate internal representation. If not, ASCII/Latin-1 is appropriate. Anything Eggs that do conversion will need to convert between arbitrary encodings in byte vectors and UTF-8 strings. So at worst, some eggs might need to be split in two.

I would say that UTF-8 has *more* chance of causing undetected breakage, because UTF-8 strings have an interpretation as core strings, whereas bignums, ratnums, compnums etc. don't look like numbers to the core, and errors will be thrown. -- John Cowan http://www.ccil.org/~cowan co...@ccil.org Police in many lands are now complaining that local arrestees are insisting on having their Miranda rights read to them, just like perps in American TV cop shows. When it's explained to them that they are in a different country, where those rights do not exist, they become outraged. --Neal Stephenson _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
