BpmfGenSenRounded is a Bopomofo IVS build of GenSen Rounded: each Han
character that has more than one Bopomofo reading carries Ideographic
Variation Sequences and Private Use Area glyphs that render the character
together with its reading.

Input methods that implement the Bopomofo IVS specification, such as
chinese/fcitx5-mcbopomofo in its Bopomofo font annotation mode, use these
fonts to produce Bopomofo-annotated text for teaching material and
publishing.
