note 86863 added to function.mb-convert-encoding

A common problem that people seem to be running into with mb_convert_encoding (and one that I had myself) is that it converts characters which are invalid for the target encoding into question marks (?), this is obviously not very useful when trying to present information to a user. A quick and dirty solution that produces results similar to iconv() is shown below: ------------------------------------------------ function convert_to ( $source, $target_encoding ) { // detect the character encoding of the incoming file $encoding = mb_detect_encoding( $file, "auto" ); // escape all of the question marks so we can remove artifacts from // the unicode conversion process $target = str_replace( "?", "[question_mark]", $source ); // convert the string to the target encoding $target = mb_convert_encoding( $target, $target_encoding, $encoding); // remove any question marks that have been introduced because of illegal characters $target = str_replace( "?", "", $target ); // replace the token string "[question_mark]" with the symbol "?" $target = str_replace( "[question_mark]", "?", $target ); return $target; } Hope this helps someone! ---- Server IP: 216.235.15.211 Probable Submitter: 99.231.148.142 ---- Manual Page -- http://www.php.net/manual/en/function.mb-convert-encoding.php Edit -- https://master.php.net/note/edit/86863 Del: integrated -- https://master.php.net/note/delete/86863/integrated Del: useless -- https://master.php.net/note/delete/86863/useless Del: bad code -- https://master.php.net/note/delete/86863/bad+code Del: spam -- https://master.php.net/note/delete/86863/spam Del: non-english -- https://master.php.net/note/delete/86863/non-english Del: in docs -- https://master.php.net/note/delete/86863/in+docs Del: other reasons-- https://master.php.net/note/delete/86863 Reject -- https://master.php.net/note/reject/86863 Search -- https://master.php.net/manage/user-notes.php
