>From etc/NEWS:

     ** skip-chars-forward and skip-chars-backward now handle
     character classes such as [:alpha:], along with individual characters
     and ranges.

The Elisp Manual still has the following sentence:

     Note that char classes are not currently supported in
     CHARACTER-SET; they will be treated as literals.  Thus you cannot
     use `"[:alpha:]"' instead of `"a-zA-Z"' to include non-ASCII
     letters.  A way to skip forward over all letters is:

          (re-search-forward "\\=[[:alpha:]]*" nil t)

This seems to be obsolete now.
