OK, now, supposing that the unicode license is found to be non-DSFG
free, and hence that UnicodeData.txt is non-free.

Suppose a program implements either unicode collation, regular expressions, 
or any of the other things mentioned above.

(collation is at: http://www.unicode.org/unicode/reports/tr10/,
regular expressions are at http://www.unicode.org/unicode/reports/tr18/)

Can the program be in debian main?

In other words, does the program "require ... non-free packages or
packages which are not in our archive at all for ...  execution"?
