This character is a Uppercase Letter and is commonly used, that is, in no specific script.
The glyph is a compatibility version of the glyph Glyph for U+0190Latin Capital Letter Open E. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+2107 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
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."
