Representations
Under normal orthographic rules, it has no uppercase form as no word begins with this letter. However, Cyrillic type fonts do normally provide an uppercase form for setting type in all caps, or for using it as element of various serial numbers (like series of Soviet banknotes) and indices (for example, there once existed a model of Old Russian steam locomotives marked "Ь" — ru:Паровоз Ь).
In the romanization of Cyrillic words, soft signs are typically replaced with the prime symbol ′ (or, alternatively, apostrophe) or just ignored, if in a position where it does not denote iotation: Тверь=Tver, Обь=Ob etc.
