The default charset of get_html_translation_table() is ISO-8859-1 for versions of PHP prior to 5.4.0 (http://php.net/manual/en/function.get-html-translation-table.php).

We've detected the problem because some forum emails (those with html entities) were not being sent because a database error (MySQL):

Incorrect string value: '\xA0\xA0\xA0\xA0\xA0\xA0...' for column 'fullmessage' at row 1

To fix the problem pass the encoding parameter to get_html_translation_table():

get_html_translation_table(HTML_ENTITIES, ENT_COMPAT|ENT_HTML401, 'utf-8');

Maybe other versions of moodle and other components are affected by this bug.

has a non-specific relationship to

MDL-37068 question format learnwise is not utf-8 compatible
