[pmwiki-users] Can't save some Chinese wiki word page.

[Elias Soong]

A man named henry on the Chinese page of www.pmwiki.org said, if a page
named as some special Chinese word, this page will not be save.

I have tested it. If name a page as %e7%ba%a2 (the UTF-8 value of a
Chinese page name), and when click the submit, then server say:

----

Warning: fopen(wiki.d/Main.红,new) [function.fopen]: failed to create
stream: Invalid argument in D:\www\pmwiki2\pmwiki.php on line 578

PmWiki can't process your request
Cannot write page to Main.红 (wiki.d/Main.红)...changes not saved

We are sorry for any inconvenience.

This only happen on PHP at windows platform, and may only for Chinese
windows platform. On linux, all Chinese word is ok. So we think it is a
bug for PHP.

A work a round is, at the line 578, 590 and 592, change "$pagename,new"
to be "$pagename"."_new", all words will be ok. If we change it to be
"$pagename".",new" or "$pagename".".new", it still the same problem.

Maybe we should change the temporary file naming method for this
problem. Thanks a lot.
