Support for ℟ and ℣

I would like to ask for addition of two barred glyphs:
- ℟ Response (U+211F)
- ℣ Versicle (U+2123)

Usage
----
- Those glyphs are used in latin liturgical books of Roman Catholic Church. They indicate change of person in a dialog.
- Interestingly, in various books the small-caps variants of those glyphs are used, yet none of a typeface supporting ℟ and ℣ provides smcp variants.
- Both glyphs are (almost) always succeeded with a period.

A bar shape
----
There are three main bar shapes used in books:
- L-shaped (like in Times New Roman)
- J-shaped
- integral symbol ∫-shaped
