Where in the draft databases for Unicode 10.0 is Unicode 9.0 variation sequence <U+0031, U+FE0E> declared legitimate? Without such a declaration, a font that had a special glyph for <U+0031, U+FE0E> or a substitution specific to <U+0031, U+FE0E, U+20E3 COMBINING ENCLOSING KEYCAP> would not be Unicode compliant.
I hope this reflects my ignorance of the definition system rather than an error in the databases. Richard.
