Character'Val does the same thing.

Character'Pos does the same thing.

No conversion should be necessary. Character'Pos returns a universal 
integer, which is implicitly converted.

No conversions are necessary. C (...) is already of type Unsigned_8, and 
16#FF#, an integer literal, may be used with any integer type without 
conversion.
