问题
How do I post symbols (eg. ©) in a wall post using the graph api? Html entities (eg. ©) aren't parsed in facebook.
回答1:
All large text fields are utf-8, use the actual character used to represent it which is U+00A9
If you have HTML entities you can decode with html_entity_decode()
$utf8_text = html_entity_decode("test © foo", ENT_COMPAT, "UTF-8");
