Any compiler which takes 'char' as 'unsigned' ?

Question

Is there any C compiler which takes the default type of char as unsigned unless explicitly mentioned by the user in the file or project settings?

Answer 1

The standard requires that the integer value of all characters required by the standard (A-Z, a-z, 0-9, basic punctuation, etc.) be positive, so any system using an encoding where these characters' values are outside the range of signed char must have plain char be unsigned. I believe this means all EBCDIC systems must have a plain char that's unsigned, but I may be mistaken.
