.Net regex: what is the word character \w?

by

From the documentation:

Word Character: \w

\w matches any word character. A word character is a member of any of the Unicode categories listed in the following table.

  • Ll (Letter, Lowercase)
  • Lu (Letter, Uppercase)
  • Lt (Letter, Titlecase)
  • Lo (Letter, Other)
  • Lm (Letter, Modifier)
  • Nd (Number, Decimal Digit)
  • Pc (Punctuation, Connector)
    • This category includes ten characters, the most commonly used of which is the LOWLINE character (_), u+005F.

If ECMAScript-compliant behavior is specified, \w is equivalent to [a-zA-Z_0-9].
