I18N question

[Jeszenszky Peter <jeszy inf unideb hu>]

Hello,

I'm working on a Java application that extracts package metadata from RPM
packages and transforms it to RDF, making RPM metadata available to
Semantic Web applications.

My question is about the RPMTAG_HEADERI18NTABLE header tag. The value of
this tag is a string array that has only one element ("C") in each RPM
package that I have seen. Is this I18N feature really supported in RPM-
aware software? May I assume that every string in the header is encoded
in plain old US-ASCII?

Best regards,

Peter
