IRIs: Internationalized URIs
  - URIs (Universal/Uniform Resource Identifiers): Core component of the
  WWW
- Example: http://www.w3.org/2003/Talks/0904-IUC-IRI
- IRIs:
    
      - Allow characters outside US-ASCII
- Use UTF-8 and %HH-escaping for conversion to URIs
- Otherwise work the same way as URIs
 
- Background/motivation: see IUC19
