Does Factor support Unicode?
There is no one meaning to the phrase “Unicode support”, but there are a few things that a modern programming language is expected to support in its library: UTF-8/UTF-16 input and output, Unicode collation, Unicode-appropriate casing operations, normalization, and UI support for Unicode input and output. Of these, Factor supports all but collation and UI support, both of which are in the works and should be finished before 1.0 comes out. All Factor strings can hold any Unicode code point, and it's planned that strings will be consistently held in Normalization Form D.
