Subject: Re: Found a ruby bug in the URI class, what do I do?

Sorry, Victor, but yes it does.

Quoting from the end of RFC 2396 section 2.4.3:

[quote]
Other characters are excluded because gateways and other transport  
agents are known to sometimes modify such characters, or they are used  
as delimiters.
  unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"
Data corresponding to excluded characters must be escaped in order to  
be properly represented within a URI.
[/quote]

So that last sentence pretty much nails it. Curly braces "...must be  
escaped in order to be properly represented within a URI."

So you'll have to continue to escape them yourself. It wouldn't be  
right for the URI class to depart from the standard here.
