U+1D51 Modifier Letter Small Eng

U+1D51 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 Eng. 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+1D51 forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

In phonetics, nasalization (or nasalisation) is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. An archetypal nasal sound is [n].
In the International Phonetic Alphabet, nasalization is indicated by printing a tilde diacritic U+0303 ◌̃ COMBINING TILDE above the symbol for the sound to be nasalized: [ã] is the nasalized equivalent of [a], and [ṽ] is the nasalized equivalent of [v]. A subscript diacritic [ą], called an ogonek or nosinė, is sometimes seen, especially when the vowel bears tone marks that would interfere with the superscript tilde. For example, [ą̄ ą́ ą̀ ą̂ ą̌] are more legible in most fonts than [ã̄ ã́ ã̀ ã̂ ã̌].
