I need a regular expression that matches UTF-8 letters and digits, the dash sign (-) but doesn't match underscores (_), I tried these silly attempts without success:

  • ([\w-^_])+
  • ([\w^_]-?)+
  • (\w[^_]-?)+

The \w is shorthand for [A-Za-z0-9_], but it also matches UTF-8 chars if I have the u modifier set.

Can anyone help me out with this one?
