Ḥ

Ḥ (minuscule: ḥ) is a letter of the Latin alphabet, formed from H with the addition of a dot diacritic. The letter has significance in various writing systems.

These include:

Visarga, the phone [h] in Sanskrit phonology in the International Alphabet of Sanskrit Transliteration. Other transliteration systems use different symbols.
Transliteration of Heth or Ḥet, the reconstructed name of the eighth letter of the Proto-Canaanite alphabet, which in Modern Israeli Hebrew usually has the sound value of a voiceless uvular fricative (/χ/), as in Ashkenazi Hebrew. In other phonologies, such as Arabic and in some Syriac languages (such as Turoyo and Chaldean Neo-Aramaic), it is pronounced as a voiceless pharyngeal fricative (/ħ/) and is still among Mizrahim (especially among the older generation and popular Mizrahi singers), in accordance with oriental Jewish traditions.
The phone [h] (voiceless glottal fricative) or [x] (voiceless velar fricative) in the Asturian language.
