Is there anything

more embarrasing than reinventing the wheel? Today I found out that I had written functions to convert from character to ascii code and vice versa, as well as test a character's printability, while they were in my standard library all along. The only thing that makes me feel better is that I looked before writing them and simply failed to find the library functions, rather than re-inventing the wheel without thinking.

from character to ascii code
If it doesn't support all of Unicode, it's already obsolete.

as well as test a character's printability
There's so much more information and semantics you can access to for any character if you use the proper character sets and standards.
