Just read his post. Works for me, and with a little luck and possibly a few tweaks if/as discovered through use to be nice/required, it could win broader acceptance. (although I suspect that it may be found necessary to base read-char, read-string, etc. on a flexibly defined "local" encoding definition, rather than assuming all text/data is encoded any particular way, on any particular platform.) where with a: (bytes->value <bytes> <encoding>) -> <value> and matching: (value->bytes <value> <encoding>) -> <bytes> then multiple <encoding> procedures may be defined as desired/required, which could default to "local" definitions if not explicitly specified. thereby enabling any arbitrary sequence of encoded bytes read/written from/to a port to be converted to/from a generic internal scheme value type, using whatever external encoded representations may be required.
