There are a few problems with this post:
1. You stated that the underscore character ("_") is non-matching, but clearly it DOES match, because it is included the the \w directive. Try putting "hello_there" in the test page and you'll see.
2. Instead of using a space character in the match group, for a generic pattern like this it is better to use the whitespace directive ("\s"), so that things like tabs are matched.
3. Instead of using "{0,}", you should use the asterisk ("*"). It is much easier for someone to read and understand with a single asterisk character, and it probably compiles better across all regex flavors.
The final pattern should be "^[\w\s]*$"
