If the result is not ligated, a virama is visible, attached to C1, actually written. Basically, those differences are only glyph variants, and three forms are semantically identical. Although there may be a preferred form for a given consonant cluster in each language and some scripts do not have some kind of ligatures or half forms at all, it is generally acceptable to use a nonligature form instead of a ligature form even when the latter is preferred if the font does not have a glyph for the ligature. In some other cases, whether to use a ligature or not is just a matter of taste. The virama in the sequence C1 + virama + C2 may thus work as an invisible control character to ligate C1 and C2 in Unicode. For example, is a fully conjoined ligature. It is also possible that the virama does not ligate C1 and C2, leaving the full forms of C1 and C2 as they are: is an example of such a non-ligated form. The sequences ङ्क ङ्ख ङ्ग ङ्घ , in correct Devanagari handwriting, should be written as conjuncts (the virama and the top cross line of the second letter disappear, and what is left of the second letter is written under the ङ and joined to it). The inherent vowel is not always pronounced, in particular at the end of a word (schwa deletion). No virama is used for vowel suppression in such cases. Instead, the orthography is based on Sanskrit where all inherent vowels are pronounced, and leaves to the reader of modern languages to delete the schwa when appropriate.
