Thank you very much. :-)

My proposed hack(yes, no solution) just works for me but I found that it is just wrong w.r.t RFC.

I'll try your modification and and let you know whether it works or not.

Thank you again.

Hi Sungjin,

   Thanks for trying to use the uri-generic library. As Peter already  pointed out, uri-generic and uri-common are intended to implement RFC 3986 (URIs), and so far no effort has been done to support RFC 3987 (IRIs).

Interesting, I wasn't even aware of RFC 3987.  Note that this extension

only applies to new schemes - in particular IRIs cannot be used for HTTP.

 

However, the IRI RFC does define a mapping from IRI to URI, where Unicode characters in IRIs are converted to percent  encoded UTF-8 sequences. The caveat here is that if you try to decode these percent-encoded sequences they will likely result in invalid URI characters. I have prototyped a procedure iri->uri which attempts to percent-encode all UTF-8 sequences in the input string and create a URI. You can see it here:

This shouldn't be needed.  Sungjin was using uri-common, which already

percent-encodes UTF-8 sequences, which is what is desired.

Sungjin - going back to your original question, what did you try and

what did it do differently from what you expected?  This should just be

working.
