RE: [xri] XRI Escaping Tool

["Wachob, Gabe" <gwachob@visa.com>]

What browser were you using?

 

I'll try this myself as well - I think I might know whats going on (I htink this is due to poorly standardized unicode behavior between browsers).

 

    THANKS

Cool!

 

I tried it on the string "@ a-la-française" and got the error below.

For my own understanding, and as a service to the XRI community, I have written a tool to implement what I understand to be the XRI to URI transformation rules. If you input an XRI with unicode (or just ascii) characters, it will display the IRI-normal and URI-normal forms. This obviously requires a utf-capable OS & browser, which is most of them these days. Tested on firefox 1.0 and IE6.

Please do try it. I've implemented this using the python unicode facilities and the escaping rules as I interpret them. I would like everyone to try this out themselves and please report back a) if the results are what you expect and b) if you see any hiccups.

 

I think one of the most complicated facets of XRI syntax is the escaping rules, but they are critical for interoperability, so please do hammer away.

P.S. I will, of course, publish source code once I get a feeling that its producing results that seem to be agreeable with everyone.
