About character encoding
In general we use UTF-8 as default character encoding.
The AC->settings->encoding is 'utf-8' unless overriden in autocomplete_config.php The text.php is saved as UTF-8 The css file uses '@charset "utf-8";'
We have to support other encodings like iso-8859-1 because some collections are not utf-8 encoded.
UTF-8 lowercase in PHP (23May07 Markus)
Requires extension mbstring (for functions like mb_strtolower). Following line required in php.ini
In windows: extension=php_mbstring.dll or in linux: extension=php_mbstring.so
(On geek, the mb_... functions were available by default, on Markus's laptop the line above had to be added.)
