180                     * quote from version 2.1:
181                     *
182                     * "It is recommended that this be a numeric representation
183                     * if possible (ISO standards, especially), not include
184                     * additional punctuation symbols, and that any letters be
185                     * in lowercase."
186                     *
187                     * Any sane standard would use directory names like
188                     * de_DE.ISO-8859-1; the examples in the FHS recommend
189                     * de_DE.88591 instead. Considering that there is no other
190                     * conceivable use for encodings in directory names other
191                     * than to pass them to iconv or similar, this is quite
192                     * startlingly useless.
193                     *
194                     * My plan is to ignore the current FHS specification on the
195                     * grounds that it's obviously wrong, and petition to have
196                     * it changed.
