Problem with non-Latin filenames

Hi,

I’m a long time user of WPSC so am very familiar with it. But I’ve now run into an issue that I can’t seem to fix myself.

I got a site in ARABIC, and the permalink structure is /%postname%/

In the supercache dir, however, some posts are saved correctly as urlencoded whereas some are not urlencoded. It seems to be random.

So I got files like this (a small sample):

%d9%88%d8%b2%d9%8a%d8%b1-%d8%a7%d9%84%d8%ae%d8%a7%d8%b1%d8%ac%d9%8a%d8%a9-%d8%a7%d9%84%d8%a8%d9%88%d9%84%d9%86%d8%af%d9%8a-%d8%b1%d9%88%d8%b3%d9%8a%d8%a7-%d8%b3%d8%aa%d9%88%d8%a7%d8%ac%d9%87-%d8%b9

The problem with this is that I cannot prune the cache for the non-urlencoded posts upon update – and in fact these posts (whose cache name is not urlencoded) get stuck in the cache unless I manually delete them on the server (I am on preload mode so no GC here).

Could you help here please? Advise where to look in the plugin’s scripts? Something?

Thank you,

Bira
