Don't really understand what's going on.  I type the following into
scratch and use `M-x regex-builder` and it works exactly as I believe
you want it to.

*scratch* contents

define thisIs01Test_with-all_validChars0001

*RE-Builder* contents

define [A-Za-z0-9_-]+

Full match…

Could you provide an actual example of a string you're trying to match
that it isn't matching?
