U+0456 was added to Unicode in version 1.1 (1993). It belongs to the block Cyrillic in the Basic Multilingual Plane.

This character is a Lowercase Letter and is mainly used in the Cyrillic script. It is related to its uppercase variant І and its titlecase variant І. The character is also known as Old Cyrillic i.

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. The glyph can, under circumstances, be confused with 57 other glyphs. In text U+0456 behaves as Alphabetic regarding line breaks. It has type Lower for sentence and ALetter for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

The dotted i (І і; italics: І і ), also called decimal i, is a letter of the Cyrillic script.

It commonly represents the close front unrounded vowel /i/, like the pronunciation of ⟨i⟩ in "machine".

It is used in the orthographies of the Belarusian, Kazakh, Khakas, Komi, Rusyn and Ukrainian languages, where it is the equivalent of the Cyrillic letter i (И и) as used in Russian and other languages. (Ukrainian і is therefore Russian и, while Ukrainian uses и for a sound close to Russian ы. Belarusian meanwhile uses only і and ы, excluding и entirely. Rusyn uses і, и, and ы for three different sounds: /i/, /ɪ/, and /ɨ/ respectively.) In Komi, і occurs only after the consonants д, з, л, н, с, and т and does not palatalize them, whereas и does. In Kazakh and Khakas, і represents /ɪ/, as in "bit".

Just like the Latin letters I/i (and J/j), the dot above the letter only appears in its lowercase form, and only if that letter is not combined with a diacritic above it (notably the diaeresis used in Ukrainian to note the letter yi of its alphabet, and the macron). But even in that case (and as with the Latin letters i and j), this dot has not always been rendered in historic texts where the lowercase form was present without any other diacritic, and some modern texts and font styles may still discard this "soft" dot on the lowercase letter, because it is necessary for the readability of the text only for cursive styles.
