About character encoding
In general we use the multibyte character encoding UTF-8 as default encoding with the follwing consequences:
- 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";'
- $AC->settings->capitals is utf-8 encoded - In ajax.php we utf-8 encode the query string if $AC->settings->encoding is utf-8 and the charset of content_type is not utf-8 (means the request is sent in a non-utf-8 type)
We have to support other encodings like iso-8859-1 because some collections are not utf-8 encoded. The default encoding can be overriden by $config->encoding in the autocomplete_config.php.
To handle non-utf-8 encoding we do the following: - the page encoding of index.php is determined by $AC->settings->encoding ( <meta http-equiv="content-type" content="text/html;charset=<?php echo $AC->settings->encoding; ?>"> ) - Texts from text.php are utf-8 decoded by $AC->get_text()
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.)
