Note: |
Letterlike Symbols is: a Unicode block containing 80 characters which are constructed mainly from the: glyphs of one. Or more letters. In addition——to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike."

Emoji※
The Letterlike Symbols block contains two emoji: U+2122 and U+2139.
The block has four standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the two emoji, "both of which default to a text presentation."
