| In general we use the multibyte character encoding UTF-8 as default encoding with the follwing consequences: | = CompleteSearch = |

| * 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, options.php and change_options.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() * The way to write the javascript code in function javascript_rhs (in generate_javascript.php) depends on encoding: if no utf encoding is given the javascript is generated url encoded (this is not necessary if utf-8 is used) * We use mb_strtolower (instead of strtolower) with parameter $AC->settings->encoding to enable utf-8 == 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.) == Texts in text.php are now UTF-8 encoded (23May07 Markus) == |
