This character is a Nonspacing Mark and inherits its script property from the preceding character.
The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Nonspacing Mark. When changing direction it is not mirrored. U+E0109 prohibits a line break before it.
The Wikipedia has the following information about this codepoint:
Variation Selectors Supplement is a Unicode block containing additional variation selectors beyond those found in the Variation Selectors block.
These combining characters are named variation selector-17 (for U+E0100) through to variation selector-256 (U+E01EF), abbreviated VS17 – VS256.
As of 12 December 2017, VS17 (U+E0100) to VS48 (U+E011F) are used in ideographic variation sequences in the Unicode Ideographic Variation Database (IVD). These selectors are known as Ideographic Variation Selectors (IVS). They are not listed in the list of standardized variation sequence, instead they are listed in another Ideographic Variation Database.
