Title:
  isalpha() doesn't include Umlaute even if LC_CTYPE=de_DE.UTF-8

Status in glibc package in Ubuntu:
  Expired

Bug description:
  Hope this is the right package and not glibc: Got a bug report for
  wxMaxima that Umlaute ("öäüÄÖÜß") aren't treated as ordinary letters
  anymore. As wxMaxima uses the isalpha() command in order to see if
  something is a letter and since wxMaxima uses utf8 that meant that
  isalpha() doesn't recognize an unicode umlaut as letter anymore. Which
  solved my problem: ispell.el in emacs currently divides words at any
  umlaut.

  LC_CTYPE seems to be set correctly, though:

  gunter at marius:~$ locale
  LANG=en_US.UTF-8
  LANGUAGE=en_US:en
  LC_CTYPE=de_DE.UTF-8
  LC_NUMERIC=de_DE.UTF-8
  LC_TIME=de_DE.UTF-8
  LC_COLLATE="en_US.UTF-8"
  LC_MONETARY=de_DE.UTF-8
  LC_MESSAGES="en_US.UTF-8"
  LC_PAPER=de_DE.UTF-8
  LC_NAME=de_DE.UTF-8
  LC_ADDRESS=de_DE.UTF-8
  LC_TELEPHONE=de_DE.UTF-8
  LC_MEASUREMENT=de_DE.UTF-8
  LC_IDENTIFICATION=de_DE.UTF-8
  LC_ALL=

  ...and I definitively use UTF8.
