There is no way to provide an encoding layer to directory names.
Therefore they need to be raw bytes and not characters. This becomes
apparent when creating namespaces containing non-ASCII characters.
The Debian installation uses ext3 and therefore raw bytes for
filenames unlike the HFS filesystem of Mac OSX.
Copyright years were updated. The maintenance output of for drafts was
cleaned up.
All the source files containing non-ASCII characters needed to have
utf8 added. This will be necessary for user config files as well! The
regular expressions identifying page names had to be changed.
UrlEncode translates the string back to bytes before encoding it.
Cached RSS files are saved with UTF-8 encoding and therefore need
their meta-data changed (using the XML::RSS module to do this
correctly didn't work for some of the test files). The CGI object's
parameters, keywords and info_path are decoded correctly. File access
uses the UTF-8 layer (reading, writing, appending, access to the log
of recent changes, running sub processes with grep and diff).
The mac compatibility extension will also disable the use of grep if
non-ASCII characters are searched for because of an unexplained
problem with grep.
