Well, of course not because use of VS14 in a plain text document to
record a request for an italic glyph version is not at the present time
an official part of Unicode. The next scheduled Unicode Technical
Committee meeting is due to start on 30 April 2019.
Here is a link to the proposal document.

VS14 is used to indicate a request for an italic glyph version in my
VS14 Maquette font but that is clearly just a maquette font for
experimental use to test the concept and show that it works. An
application program that supports OpenType and that has the liga table
switched on is needed in order to use the VS14 Maquette font to
demonstrate that the use of VS14 in this way works.
