问题
I am receiving an XML response which comes through perfectly.
Words such as "português" and "españa" are correctly formatted.
However, once I have parsed the XML through the php function simplexml_load_string(), the words are transformed as follows: "portugu�s" and "espa�a".
回答1:
Simple XML always treats text internally as UTF-8 encoded, converting to and from this character set if necessary. To solve your issue either make sure that all output from your app is UTF-8 encoded or convert it to another character set (possibly using utf8decode()).
