How to serve gziped an otf font using htaccess+php.ini? (no mod gzip or deflate)

Question

Im asking this here cause if i try more i think im going to lose my mind for sure
it seems i can't use php_value or php_flag but linking a php.ini using suPHP_ConfigPath works (for php files)
here's a list of stuff i tried in random order:

AddHandler application/x-httpd-php .otf
AddType
default_mimetype
application/vnd.oasis.opendocument.formula-template
auto_prepend_file = "otf.php"
zlib.output_compression = On
output_handler = ob_gzhandler
header("Content-type: application/octet-stream");

also renaming the .otf file to .php doesn't work either (all the php file on my server get gziped using zlib)
anyone got an idea? maybe an apache/php guru?
the answer is probably a mix of the list above but apparently im not doing it correctly

With .htaccess, you could do like this, assuming font file is fontfile.otf.gz, browser request that as fontfile.otf

RewriteEngine On

#Check for browser's Accept-Encoding, remove it for force return gzipped one
RewriteCond "%{HTTP:Accept-Encoding}" "gzip.*deflate|deflate.*gzip"

#check file name is endswith otf
RewriteCond %{REQUEST_FILENAME} "\.(otf)$"

#check existance of .gz file name
RewriteCond %{REQUEST_FILENAME}.gz -s

#rewrite it to .otf.gz
RewriteRule ^.*$ %{REQUEST_URI}.gz [L]

#update some response header
<FilesMatch "\.otf\.gz$">
    AddEncoding gzip .gz
    ForceType "text/plain"
</FilesMatch>

And if font file and web site is cross-domain, you need to put Access-Control-Allow-Origin, firefox will not load font objects cross-domain.

In Gecko, web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction.

Header set Access-Control-Allow-Origin *
