Hi,

> compressors and test it in the upper layer?

I haven't used any mbstring function inside the methods that do the
compressing. But I actually have something in mind about overloading normal
string functions with mbstring functions if user wants it.
Personally, I use UTF-8 encoding for javascripts to include my local
language strings, So it may be good thing to support javascripts which are
multibyte encoded. Otherwise those scripts will be ended up with crappy
strings, after compression.

A solution will be to add a method to js compressor that will change php
ini value ''*mbstring.func_overload*" to 2 (See
http://php.net/manual/en/mbstring.overload.php) whenever user wants to
compress a mb encoded file. May be we can add a compressor option also. I
have just added a method to change mb internal encoding to 8 bit (see
https://github.com/kaviththiranga/joomla-platform/blob/JMedia/libraries/joomla/media/compressor/js.php#L322)
if php mbstrings functions are already enabled and overloading normal
string functions with mbstring functions is also enabled. See the
_changeCharEncoding() method. It actually does nothing to affect the
compression unless user manually configures php.

So I think it will not be an issue.

regarding the name : Yep, my personal idea also was to use JCompress name.
But with the suggestions from community, I decided to use JMedia, thinking
of further improvements(like more compressors) which can be done. But it
must not be the final name. We will see the feedback from others regarding
this and I'll do the modifications if majority suggests that.

regarding the integration of available libraries : Actually the original
idea was to implement 100% joomla-platform library that will handle
compression and combining. So I have tried my best to do that. I have to
mention that this library does not obfuscate javascripts. For those
advanced things, we can integrate an available library. Since I had only a
limited time, I just omitted obfuscating part . But I am hoping to continue
to work on that after GSOC.

Thanks for you feedback.
