The ascii function converts a sequence of characters into a word list of codepoints. Because EPIC only supports latin-1 at this time, all of the codepoints are 0 to 255 (strictly 1 byte per codepoint). If in the future epic supports UTF8 or something like that, codepoints greater than 255 might be returned.
You can use the chr function to convert a word list of codepoints into a sequence of characters. The same caveats about encoding applies.
/* assume iso8859-1 character set */ $ascii(abcABC) returns "97 98 99 65 66 67" $chr($ascii(abcABC)) returns "abcABC"
Some characters with the high bit set will return negative numeric values from $ascii(). Add 256 to this negative value to get its positive equivalent. The $chr() function will accept either.
