Non alphanumeric characters in `g:qs_accepted_chars`

[puneetpahuja]

I want to add non alphanumeric characters in g:qs_accepted_chars but it does not work.

# and _ seem to work but others don't. Am, I doing something wrong here?

This would be the correct way to do what you want, so there must be a bug in how target characters are interpreted.
