The Wikipedia has the following information about this codepoint:

Hiriq (Hebrew: חִירִיק ḥiriq  IPA: [χiˈʁik]) is a Hebrew niqqud vowel sign represented by a dot ⟨ ִ ⟩ underneath the letter. In Modern Hebrew, it indicates the phoneme /i/ which is the same as the "ee" sound in the English word deep and is transliterated with "i". In Yiddish, it indicates the phoneme /ɪ/ which is the same as the "i" sound in the English word skip and is transliterated with "i".

In Israeli writing a ḥiriq is often promoted to ḥiriq male (Hebrew: חִירִיק מָלֵא IPA: [χiˈʁik maˈle]) for the sake of disambiguation (see ktiv male). A ḥiriq male in Hebrew spelling is a ḥiriq under the preceding yud ⟨ִי⟩, while in Yiddish orthography the ḥiriq is placed under the yud ⟨יִ⟩. In writing without niqqud, the ḥiriq is omitted leaving only the yud ⟨י⟩. The usage of a consonant (in this case yud) to indicate a vowel comes from mater lectionis.
