Hi,

I’m accessing a web service API. This API is somehow like convert  
input string to a graph.  
this API has a text params. In the specification, this params should  
be UTF-8 encoded.  
what shall I do to ensure of this? or just pass the string to it?

The reason I’m asking is, when I pass some Chinese string to that API,  
some string works fine, some string result in “messy code” in the  
generated graph.

Any idea?

Cheers,  
Joe
