Ukrainian National transliteration it was used for make this transliteration and includes an exception:
The "Ь ь" (M'yakyi Znak or soft sign) although is not considered a letter at all, indicating the softening (palatalization) of the preceding consonant letter.
I consider it's important mark this sign and give it its respective place into the transliteration, plus it's more easy for a person who's recently is learning to read Ukrainian, Russian or Belarussian to understand this words.
