Granularity of Unicode Conformance

From: Hart, Edwin F. (

Jonathan Rosenne raises one of the problems with the description of Unicode
2.0 conformance. The chapter describes what is required for a product to
*fully* support Unicode 2.0. However, I believe that it is safe to say that
most products implement only subsets of the Unicode 2.1 repertoire and
functionality (e.g., bidi algorithm). Thus, 2 products may claim to support
Unicode 2.0 or 2.1 but each may implement different subsets and neither may
provide the support that the user expected.

However, developing some checklist to define what features of Unicode 3.0
are implemented in a particular product that claims Unicode 3.0 conformance
is a non-trivial exercise.

Since many products support Unicode but do not support bidi, I suggest it
would be useful if for those who do it would be indicated.
