std.ascii

Functions which operate on ASCII characters.

All of the functions in std.ascii accept Unicode characters but effectively ignore them if they're not ASCII. All isX functions return false for non-ASCII characters, and all toX functions do nothing to non-ASCII characters.

For functions which operate on Unicode characters, see std.uni.
