U+02ED Modifier Letter Unaspirated

U+02ED was added in Unicode version 3.0 in 1999. It belongs to the block U+02B0 to U+02FF Spacing Modifier Letters in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Modifier Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+02ED forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

In linguistics, a tenuis consonant ( or ) is an obstruent that is voiceless, unaspirated and unglottalized.
In other words, it has the "plain" phonation of [p, t, ts, tʃ, k] with a voice onset time close to zero (a zero-VOT consonant), as Spanish p, t, ch, k or English p, t, k after s (spy, sty, sky).
For most languages, the distinction is relevant only for stops and affricates. However, a few languages have analogous series for fricatives. Mazahua, for example, has ejective, aspirated, and voiced fricatives /sʼ sʰ z/ alongside tenuis /s/, parallel to stops /ɗ tʼ tʰ d/ alongside tenuis /t/.
Many click languages have tenuis click consonants alongside voiced, aspirated, and glottalized series.
