+
+   What do
+
+      Torbjörn Granlund    (coreutils)
+      François Pinard      (coreutils)
+      Danilo Šegan         (gettext)
+
+   have in common?
+
+   A non-ASCII name. This causes trouble in the --version output. The simple
+   "solution" unfortunately mutilates the name.
+
+     $ du --version | grep Granlund
+     Écrit par Torbjorn Granlund, David MacKenzie, Paul Eggert et Jim Meyering.
+
+     $ ptx --version | grep Pinard
+     Écrit par F. Pinard.
+
+   What is desirable, is to print the full name if the output character set
+   allows it, and the ASCIIfied name only as a fallback.

+
+     $ LC_ALL=C recode-sr-latin --version
+     ...
+     Written by Danilo Segan and Bruno Haible.
+
+   The 'propername' module does exactly this. Plus, for languages that use
+   a different writing system than the Latin alphabet, it allows a translator
+   to write the name using that different writing system. In that case the
+   output will look like this:
+      <translated name> (<original name in English>)
+
+   To use the 'propername' module requires two simple steps:
+
+     1) Add it to the list of gnulib modules to import,
+
+     2) Change the arguments of version_etc(),
+
+          from "Paul Eggert"
+          to   proper_name ("Paul Eggert")
+
+          from "Torbjorn Granlund"
+          to   proper_name_utf8 ("Torbjorn Granlund", "Torbj\303\266rn Granlund")
+
+          from "F. Pinard"
+          to   proper_name_utf8 ("Franc,ois Pinard", "Fran\303\247ois Pinard")
+
+        (Optionally, here you can also add / * TRANSLATORS: ... * / comments
+        explaining how the name is written or pronounced.)
