The 1.1.1 build was built with the yui-compressor. It resulted in about 12k drop in file size. I also used it for the CSS.

The YUI Compressor is under heavy developement.
At time of writing the latest version is 2.1.1 and can be obtained from a new url:
Please be aware that for you'll explicitly need to enable --charset utf-8 with yui-compressor to build a completely working extjs.
This is a bug that i've also reported in the Bug Forums for the Ext 1.1.1 build.
The locale files use UTF-8 encoding to support many non-ascii languages. The yui-compressor does not automaticly detect the correct character encoding for these files and tries to decode them with a ascii charset. This results in all non-ascii characters being mangled into ascii character 63 - the question mark.
ah just replied to trbs in the bugs thread...
[copied and pasted from bugs]
got this from the YUI Compressor download page:
If a supported character set is specified, the YUI Compressor will use it
to read the input file. Otherwise, it will assume that the platform's
default character set is being used. The output file is encoded using
the same character set.
For completeness sake; my Debian Linux appearenly defaults to ASCII as does Jack's Windows Vista machine appearently, since the official build sports the same problem.
