U+1D4A was added in Unicode version 4.0 in 2003. It belongs to the block U+1D00 to U+1D7F Phonetic Extensions in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Modifier Letter and is mainly used in the Latin script.

The glyph is a superscript version of the glyph Latin Small Letter Schwa. 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+1D4A forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Ə, or ə, also called schwa, is an additional letter of the Latin alphabet. In the International Phonetic Alphabet (IPA), minuscule ə is used to represent the mid central vowel or a schwa.
It was invented by Johann Andreas Schmeller for the reduced vowel at the end of some German words and first used in his 1820s works on the Bavarian dialects.
