I am trying to retrieve a unicode string using librdf_node_to_string
passing the node pointer into the function.
However, I am getting back a messed up string:
Expected return: [!+'#[]Ü¥ƒ&,;
What I am getting: [!+’#[]Ü¥ƒ&,;
Hard to tell what that is given the encodings of email systems and
transcoding. It should be UTF-8 out because that's what redland uses
for everything; it doesn't change encodings in either direction.
Also if you are not calling this from C (you don't say), there may
be another layer of software (SWIG + the script language)
Can anybody help? Does librdf_node_to_string handle Unicode? I know
the source where I am retrieving the string is good.
That function really mostly for debugging since it adds punctuation
like '[' and ']' around URIs.
More likely you'll use
http://librdf.org/docs/api/redland-node.html#librdf-node-get-literal-value-as-counted-string
for example, when you know it's a literal
http://librdf.org/docs/api/redland-node.html#librdf-node-is-literal
i.e.
if(librdf_node_is_literal(n)) {
size_t len;
string=librdf_node_get_literal_value_as_counted_string(n, &len);
... do something ...
}
which is actually what librdf_node_to_string()
via librdf_node_to_counted_string() essentially does (but more efficiently)
Please provide a small code example and file a bug on bugs.librdf.org
Thanks
