Inspired by "A Notation for Character Collections for the WWW" (W3C Note), 
JTC1 has developed 19757-7 Character Repertoire Description Language.

I do not know if 19757-7 will be publicly available.  But an implementation 
is already available at:


This works in Windows.  I believe that it requires .Net framework  2.0.

This zip file contains an executable file and test schemas.  Most of the
test schemas are borrowed from 19757-7, and they cover 8859-15,  8859-6,
Armenian, Malayalam, kyoiku1, and kyoiku2.

The syntax of the command is as follows:

  CREPDL schemaURI textFileName

The textFileName may be followed by an encoding name of .Net.  This 
program reports either True, False, or Unknown.

Your feedback is very much welcome.

I am hoping that XSD, RELAX NG, OOXML, ODF, Schematron, and some W3C
specs (such as forms) use CREPDL for checking characters.

If you can read Japanese, the mail thread starting at :


is useful.
