U+02F9 Modifier Letter Begin High Tone

U+02F9 was added in Unicode version 4.0 in 2003. 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+02F9 forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Spacing Modifier Letters is a Unicode block containing characters for the IPA, UPA, and other phonetic transcriptions. Included are the IPA tone marks, and modifiers for aspiration and palatalization. The word spacing indicates that these characters occupy their own horizontal space within a line of text. Its block name in Unicode 1.0 was simply Modifier Letters.
