Fix: VS15 hides non-Emoji Negative Squared Latin Capital Letter

Fix: VS15 hides non-Emoji Negative Squared Latin Capital Letter

The non-emoji letters form Negative-Squared-Latin-Capital-Letter become invisible
when use VS16 or Emoji Color Font.

Examples:
   "1F170 ~ 1F174 with variation selector, text vs emoji: 🅰️🅱️🅲︎🅳︎🅴︎\n"
   "1F170 ~ 1F174 with VS15: 🅰︎🅱︎🅲︎🅳︎🅴︎\n"
   "1F170 ~ 1F174 with VS16: 🅰️🅱️🅲️🅳️🅴️\n";

In Negative-Squared-Latin-Capital-Letter from enclosed-alphanumeric-supplement,
The Letters A,B,O,P are Emoji Variation Sequences.
