Regular expression that includes all keyboard characters except '~' and ','

Question

How do I write a regular expression that includes all keyboard characters except '~' and ','?

Answer 1

umm, like this?

[^~,]

Now to exclude characters not in keyboard, I believe you gotta include them all,

[a-zA-z0-9\t\n ./<>?;:"'`!@#$%^&*()[]{}_+=-|\\]

which pretty much covers it but looks like a crazy way to get things done. Maybe the problem definition can help you add more stuffs to exclude in the first list [^~,] than try to create a huge list of all keyboard chars

Answer 2

Different keyboards have different characters on them.

Answer 3

You didn't say what language/tool you're using, but in Java I would go with this regex:

"[\\p{Print}&&[^~,]]"

That's the intersection of two sets: all printing ASCII characters, and all characters that aren't a tilde or a comma.
