If the charset/encoding of your wiki is ISO-8859-1/Latin-1/Windows-1252 <br>
or another 8-bit encoding, \x80-\xff are the characters in the code page <br>
between 128 and 255, see <br>
<a href="https://en.wikipedia.org/wiki/ISO/IEC_8859-1#Code_page_layout" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/ISO/IEC_8859-1#Code_page_layout</a><br>
<br>
If you have enabled UTF-8 (variable-length, 8-32 bits/character) for <br>
your wiki, it is a different code page, with characters \x20-\x7f are <br>
the same as in most 8-bit code pages (ASCII) and the others are 2, 3 or <br>
4 bytes for one character but all come from the \x80-\xff range.<br>
<br>

<br>
Exclamations, equals, plus, and hash is strongly recommended to NOT <br>
enable because these characters have different meanings in URL <br>
addresses, and in PmWiki.<br>
<br>
The exclamation sign is a stop-mark for a link, a hash signifies <br>
internal anchor or ajax subpage, plus is the standard encoding of <br>
spaces, and equals start values of URL parameters.<br>
<br>
If you do enable these, many other things may and will break, and we <br>
currently don't have the potential to support such configurations.<br>
<br>
There is no such thing as \x{014C}, in the UTF-8 encoding these are the <br>
2 bytes \xc5 and \x8c and in your range you would write these <br>
\\xc5\\x8c. The small letter would be \\xc5\\x8d so the range would look <br>
like \\xc5\\x8c\\x8d (no need to repeat \\xc5). If it is not the UTF-8 <br>
encoding, it depends if the current code page contains this character, <br>
for example the iso8859-4 code page contains these Ōō characters at <br>
single bytes \xd2 and \xf2:<br>
<br>
<a href="https://en.wikipedia.org/wiki/ISO/IEC_8859-4" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/ISO/IEC_8859-4</a><br>
<br>
so if your wiki is in iso8859-4 then you could add the range \\xd2\\xf2. <br>
Enabling this could be as easy as adding to config.php<br>
<br>
$Charset = "ISO-8859-4";<br>
<br>
but your local configuration files, if they contain the international <br>
characters, need to be saved in the same encoding, see:<br>
<br>
<a href="https://www.pmwiki.org/wiki/PmWiki/LocalCustomizations#encoding" rel="noreferrer" target="_blank">https://www.pmwiki.org/wiki/PmWiki/LocalCustomizations#encoding</a><br>
<br>
If the international characters are not in the code page of the wiki, <br>
they cannot be enabled, browsers cannot post such files correctly. The 2 <br>
characters are not in the Latin-1/iso8859-1 code page.<br>
<br>
If this is a vital requirement for file names, you may try enabling <br>
UTF-8 for your wiki, then browsers will be able to both post files and <br>
pages (wikitext, pagenames, categories) with the international <br>
characters without transforming these to HTML entities.<br>
<br>
However, moving a wiki to UTF-8 is not easy if you already have uploaded <br>
files with international characters, or pagenames with these, and you <br>
may have some difficulties if the file system of the server is not <br>
Unicode.<br>
<br>
Or, you could try enabling some 8-bit encoding which does contain these <br>
characters, but again, if it is not the same as the encoding on your <br>
file system, using a file/ftp browser may not show the correct <br>
characters, and a file uploaded via FTP with such characters in the name <br>
may not be visible on the wiki.<br>
<br>
If it is not a fatally important requirement to have these characters in <br>
the filenames on the server, but you are annoyed when people upload <br>
files which appear with broken names, I can suggest a custom <br>
$MakeUploadNamePatterns array that will replace Ōō with Oo in the file <br>
name (not the text inside the file) when a file is uploaded. Enabling <br>
this will probably break existing links in the wiki to already uploaded <br>
files with these characters, and these may need to be renamed.<br>
<br>
There is no easy solution unfortunately.<br>
