note 125548 added to function.quoted-printable-decode

If you're getting black diamonds or weird characters that seemingly block an echo but still encounter strlen($string) > 0 you're probably encountering an encoding issue. Unlike the people writing ENCODE functions on a DECODE page I will actually talk about DECODE on a DECODE page. The specific problem I encountered was that an email was encoded using a Russian encoding (KOI8-R) though I output everything as UTF-8 because: compatibility. If you try to do this with a Russian encoding: <?php echo quoted_printable_decode('=81'); ?> You'll get that corrupted data. I did a couple of tests and it turns out the following is how you nest the mb_convert_encoding function: <?php echo '<p>Test: "'.mb_convert_encoding(quoted_printable_decode('=81'), 'UTF-8', 'KOI8-R').'".</p>'; ?> Unfortunately I could not find a character mapping table or anything listed under RFC 2045 Section 6.7. However I came across the website https://dencode.com/en/string/quoted-printable which allows you to manually choose the encoding (it's an open source site, they have a GIT repository for the morbidly curious). As it turns out the start of the range is relative to the encoding. So Latin (ISO-8859-1) and Russian (KOI8-R) will likely (not tested this) encode to different characters **relative to the string encoding**. ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.156.130 (proxied: 193.27.12.44) ---- Manual Page -- http://php.net/manual/en/function.quoted-printable-decode.php Edit -- https://master.php.net/note/edit/125548 Del: integrated -- https://master.php.net/note/delete/125548/integrated Del: useless -- https://master.php.net/note/delete/125548/useless Del: bad code -- https://master.php.net/note/delete/125548/bad+code Del: spam -- https://master.php.net/note/delete/125548/spam Del: non-english -- https://master.php.net/note/delete/125548/non-english Del: in docs -- https://master.php.net/note/delete/125548/in+docs Del: other reasons-- https://master.php.net/note/delete/125548 Reject -- https://master.php.net/note/reject/125548 Search -- https://master.php.net/manage/user-notes.php
