[Oberon] CHAR to/from BYTE conversion

[Jörg Straube]

Don't open that can of worms :-)
- Should LEN(s) return the number of characters in s (logical length) or the number of bytes of s (physical length)?
- shoudn't the type CHAR better be called "ASCII"?
- As Unicode characters need up to 32 bit, should CHAR be 32 bit?

Strings are quite tricky, especially a compact internal representation of them.
