Bug ID: 60174
Summary: HtmlFormatter class doesn't use fallback for
mb_convert_encoding if mbstring is not available

MediaWiki doesn't require PHP to have support for mbstring [1] (it has fallback
functions to handle that)
The HtmlFormatter class, part of MediaWiki core in MediaWiki 1.22 that's being
used only by Mobile Frontend for now, is accessing "mb_" PHP functions that
aren't being defined as fallback, giving fatal errors when PHP doesn't have
mbstring support.
The missing function is mb_convert_encoding
We should provide a fallback function for it, or check if ( function_exists(
'mb_convert_encoding' ) ) before using it (as it's being done in
DatabasePostgres.php line 437
It currently breaks Mobile Frontend on installations without mbstring
