mPDF Manual – Fonts & Languages

Input encoding

mPDF accepts UTF-8 encoded text by default for all functions.

You can use the following to allow you to write html code encoded in other than utf-8 (in functions like WriteHTML()):


$mpdf->allow_charset_conversion=true;  // Set by default to TRUE


If $allow_charset_conversion is TRUE mPDF will also read the charset from the HTML header if present e.g.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Alternatively, you could convert the html to utf-8 encoding before passing it to mPDF, using any one of the PHP functions:

  • `utf8_encode($ansi_encoded_html)` // only converts ISO-8859-1 to UTF-8
  • `iconv('windows-1252', 'UTF-8', $ansi_encoded_html)`
  • `mb_convert_encoding($ansi_encoded_html, 'UTF-8', 'windows-1252') `

Note the different order of the parameters, and the different codepage names used by the different functions. The codepage names recongnised vary from platform to platform, and your PHP configuration.

A list of codepages recognised by iconv() can be found at

In PHP5 you can list the codepages recognised by mb_ functions using mb_list_encodings().

Also note that each function has different ways of failing if illegal characters are encountered.
