65: Unrecognized character encoding
You have specified a character encoding as
charset parameter in a data URI. Unfortunately your PHP distribution does not know this character encoding.
Many character encodings are known under various aliases. For example, ISO-8859-1 is also known as Latin1. Hence you could check whether you can work with the same encoding under a different name. If your desired encoding is not supported by your PHP distribution, you could use a different character encoding. To get a list of character encodings which are supported by your PHP distribution, upload a text file encodings.php containing nothing but the following line and open the file from your browser:
<?php echo implode (', ', mb_list_encodings ());
Aneamal only works with ASCII compatible encodings.
