problem with PCRE matching, utf-8, Greek, rewrite

[tmanolat]

Dear Maxim,
it works like a charm now.

FYI I put in nginx.conf: 
[code]
...
			if ($request_uri ~ "(*UTF8)^(.*)[\\?|&]filename=([%
,a-zA-Z0-9\x{386}-\x{3ff}_\-\.]+)(&.*)?$") {
...
[/code]

Kindest regards,
Tilemahos Manolatos

PS. @Weibin Yao: I would like to avoid "fixed" character lists, I wanted
to use ranges of characters, so the above solution seems, in my opinion,
better for matching all Greek characters
