It seems that I can't use Polish characters in post title. When I try to do it, then I can see error message: "Błąd: bad page name".
I hope it's a bug, not a feature and you fix it soon --Paweł
ikiwiki only allows a very limited set of characters raw in page names, this is done as a deny-by-default security thing. All other characters need to be encoded in
__code__format, where "code" is the character number. This is normally done for you, but if you're adding a page manually, you need to handle it yourself. --Joey
Assume I have my own blog and I want to send a new post with Polish characters in a title. I think it's totally normal and common thing in our times. Do you want to tell me I shouldn't use my native characters in the title? It can't be true
In my opinion encoding of title is a job for the wiki engine, not for me. Joey, please try to look at a problem from my point of view. I'm only user and I don't have to understand what the character number is. I only want to blog
BTW, why don't you use the modified-UTF7 coding for page names as used in IMAP folder names with non-Latin letters? --Paweł
Joey, do you intend to fix that bug or it's a feature for you? --Paweł
Of course you can put Polish characters in the title. but the page title and filename are not identical. Ikiwiki has to place some limits on what filenames are legal to prevent abuse. Since the safest thing to do in a security context is to deny by default and only allow a few well-defined safe things, that's what it does, so filenames are limited to basic alphanumeric characters.
It's not especially hard to transform your title into get a legal ikiwiki filename:
joey@kodama:~>perl -MIkiWiki -le 'print IkiWiki::titlepage(shift).".mdwn"' "Błąd" B__197____130____196____133__d.mdwn
Thanks for the hint! It's good for me, but rather not for common users
Interesting... I have another result:
perl -MIkiWiki -le 'print IkiWiki::titlepage(shift).".mdwn"' "Błąd" B__179____177__d.mdwn
What's your locale? I have both pl_PL (ISO-8859-2) and pl_PL.UTF-8, but I use pl_PL. Is it wrong? --Paweł
IkiWiki assumes UTF-8 throughout, so escaped filename characters should be
__x____y____z__where x, y, z are the bytes of the UTF-8 encoding of the character. I don't know how to achieve that from a non-UTF-8 locale. --smcv
Now, as to UTF7, in retrospect, using a standard encoding might be a better idea than coming up with my own encoding for filenames. Can you provide a pointer to a description to modified-UTF7? --Joey
The modified form of UTF7 is defined in RFC 2060 for IMAP4 protocol (please see section 5.1.3 for details).
Note: libencode-imaputf7-perl has made it into debian.
"IMAP UTF-7" uses & as an escape character, which seems like a recipe for shell injection vulnerabilities... so I would not recommend it for this particular use. --smcv
I would value some clarification, in the ikiwiki setup file I have
Ikiwiki doesn't seem to produce any errors on the commandline for this, but when I attempt to create a new post with Arabic characters from the web I get the following error :
Error: Cannot decode string with wide characters at /usr/lib/x86_64-linux-gnu/perl/5.20/Encode.pm line 215.
Should the modified regexp not be sufficient? Ikiwiki 3.20140815. --mhameed
This seems like a bug: in principle non-ASCII in
wiki_file_charsshould work, in practice it does not. I would suggest either using the default
wiki_file_chars, or digging into the code to find what is wrong. Solving this sort of bug usually requires having a clear picture of which "strings" are bytestrings, and which "strings" are Unicode. --smcv
mhameed confirmed on IRC that anarcat's patch from garbled non-ascii characters in body in web interface fixes this. --smcv
Merged that patch. Not marking this page as done, because the todo about using a standard encoding still stands (although I'm not at all sure there's an encoding that would be better). --smcv
