unicodesymbols: add general way to require a feature only for specific encodings
A feature can now be required only for specific input or font encodings:
- <feature>=enc1;enc2... Require the feature <feature> only if the
character is used in one if the specified font
or input encodings.
- <feature>!=enc1;enc2... Require the feature <feature> only if the
character is used in a font or input encoding
that is not among the specified.
