First post on the list, so please be gentle 
I asked this question on stackoverflow, but wasn’t getting any love
there, and then realised I should go to the source!
I managed to get nginx (1.0.14) compiled with the latest PCRE (8.30),
changed the rewrite rule to use UTF8, but it still fails in some cases
with unicode characters.
My rewrite rule is
location / {
try_files $uri $uri/ /index.php;
rewrite "(*UTF8)^/imgthumb/(.*)$" /timthumb.php?$1 last;
}
This works fine with images without unicode, but fails when the filename
contains unicode characters.
so
/imgthumb/src=/wp-content/uploads/8姉妹の古いマトリョーシカ.jpg&h=121&w=137&zc=1
fails
but /imgthumb/src=/wp-content/uploads/MOD0005.jpg&h=121&w=137&zc=1
works fine.
On Apache using .htaccess rewrite rule, it works with both
RewriteRule ^/imgthumb/(.*)$ /timthumb.php?$1 [L]
I noticed that the problem seems to stem from the fact that the PHP
script gets only one parameter (src) into the $_GET
array with nginx,
but with apache rewrite it’s broken down to different parameters…
Is my nginx rewrite rule wrong? Is there a way to make this work?

This a problem in rewrite handling, it inconsistently escapes $1
in some cases but not in others. And it’s not really related to
unicode, just any escaped char in uri will be enough to trigger
escaping.
This needs fixing.

Avoid using rewrites.

Thanks Maxim!

Good to know. Thanks.

Avoid using rewrites.
Or avoid using nginx, but that won’t be an ideal solution obviously.
Hope that this gets fixed some time…

Try this:
location ~ (UTF8)^/imgthumb/(.)$ {
fastcgi_pass … or whatever you use
fastcgi_param QUERY_STRING $1;
…
}

Thanks Valentin. Your suggestion sounds promising. However, I’m sorry,
but I’m not that familiar with the nginx configuration rules. How do I
point it in the location directive to my php script (which is
timthumb.php) ?
I tried something like this, but it doesn’t seem to work… I’m getting
an empty response unfortunately.
location ~ (*UTF8)^/imgthumb/(.*)$ {
fastcgi_pass unix:/var/spool/phpfpm.sock;
fastcgi_param SCRIPT_FILENAME
$document_root/timthumb.php;
fastcgi_param SCRIPT_NAME /timthumb-orig.php;
fastcgi_param QUERY_STRING $1;
}

Never mind. My mistake. I forgot to use include fastcgi_params
This seems to work !! Fantastic. Thanks so much for the suggestion
Valentin.
