s (excluding the inherent vowel) that immediately follow a consonant are written as a diacritic. For example, a Devanagari consonant in ‘base form’ in Unicode is ‘घ’ /ɡʱə/ where the inherent vowel is ‘अ’ /ə/. If the vowel ‘आ’ /aː/ were to follow this Devanagari consonant, then the ‘ा’ diacritic is attached resulting in ‘घा’. Consonants that are a part of conjunct clusters may assume a conjunct form such as ‘घ्‍ ‘ in Devanagari.

Consonant–vowel clusters

In clip fonts the ‘base form’ of a character is the conjunct form such as ‘घ्‍ ’ in Devanagari and diacritics are added to indicate that the consonant is immediately followed by a vowel (including the inherent vowel). For example, a Devanagari consonant in ‘base form’ in a clip font is ‘घ्‍ ’ /ɡʱ/. If the inherent vowel ‘अ’/ə/ were to follow this Devanagari consonant, then the ‘ा’ diacritic would be attached to it resulting in ‘घ’. Vowels that are not the inherent ‘अ’ /ə/ such as ‘आ’ /aː/ that follow this Devanagari consonant, then the ‘ा’ diacritic attaches twice, resulting in ‘घा’ with a Latin script representation of ‘Gaa’.


Consonant–consonant clusters

Devanagari consonants that are a part of conjunct clusters are written consecutively in their ‘base forms’ (unless it is the last consonant in a conjunct cluster, which is in its ‘inherent vowel form’). For example, ‘घ्य’ /ɡʱjə/ is formed by ‘घ्‍ ’, followed by ‘य्‍ ’, and followed by the ‘ा’ diacritic with a Latin script representation of ‘Gya’.

Latin script characters

A computer assumes that text written with a clip font is in the Latin script. Thus, when the font is changed to another Latin script font that is not a clip font, the Latin script characters on the keys that were used to type the text are displayed instead of text in the original Brahmic script. As a result, the clip font has to be available wherever text in Brahmic script is desired. Thus, clip fonts may not be uniformly compatible across computers and the Internet. This weakness is used as a kind of
