You provided excellent examples.  I think that just like the way my 
mail program alerted me to a codepage difference, OpenEXR should 
provide a way for the application to specify the character set which 
was used (which could include UTF-8), and a way for an application to 
see which character set was used, so that the characters can be 
appropriately transcoded by the application.  The main requirement is 
that the storage must work with simple strings.

All modern operating systems provide APIs for translating between 
character sets so OpenEXR's responsibility should go as far as storing 
the string, and the identification of its character set (which should 
have a default like iso-8859-1 which works for most users).  If the 
application does not specify the character set which is used, then 
operation would be the same as today.
