About character encoding

CompletionSearch supports ISO-8859-1 and the multibyte character encoding UTF-8. UTF-8 is the default encoding with the following consequences:

• The $AC->settings->encoding is 'utf-8' unless overriden in autocomplete_config.php

• The texts in text.php are saved as UTF-8
• The css file uses '@charset "utf-8";'

• We use mb_strtolower (instead of strtolower) with parameter $AC->settings->encoding to enable utf-8

We do the following depending on the defined encoding:

• We UTF-8 encode $AC->settings->capitals if $AC->settings->encoding is UTF-8

• 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 as a non-UTF-8 type)

• We set the page encoding of index.php, options.php and change_options.php according to $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() if $AC->settings->encoding is ISO-8859-1

• We url encode the javascript code in function javascript_rhs (in generate_javascript.php) if $AC->settings->encoding is not UTF-8 (this is not necessary if utf-8 is used)

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.)
