Clarify input encoding is ASCII/ISO-8859/UTF-8 - EBCDIC requires different constants

A tiny improvement: a*257/16 is one byte shorter than a/16|a*16.

I just saw it now, but you can also use a/16|a*16 instead of a/16|(a&15)*16. The few bits on top get removed by the &255.

In this case you can even use the format string %u instead of %hhu

I tried the challenge myself and I wrote almost exactly the same code. Btw. your program doesn't drop the bit when shifting upwards (input: !<> should result in 127 and not 255). Either define your a as char, or use the line a&=255 (and use %u) to get the correct effect. Also you can shorten your negation a^255 to ~a. a>>4&15 is also shorter than your (a&240)/16.
