Cha(rs)

Build Status

Use this tool to display names and codes for various ASCII (and unicode) characters / code points!

It's strongly inspired by ascii(1), but supports unicode characters; it's also inspired by unicode.py, but it attempts to support whitespace/control characters better.

Cha(rs) is currently probably failing at some other edge case, but I hope not.

Pronunciation

How do you pronounce "chars"? This is a contentious thing.

This package is tested on circle CI using the latest stable, beta and nightly releases. Older releases might work, but I'm focusing development mostly on the latest versions.
