Traditionally, diphthong vowels were written as a combination of vowel forms, and there were multiple forms of writing some of them. This is also true of the virama. There are also contextual variants of consonant-vowel combinations for some vowels, as is found in the
Modi script. For conjuncts, there are a few 'inherent' conjuncts found in most Indic scripts, such as
ksa, jna, and
tra, and
dra is also found in addition. Most consonants are written using the virama pattern, as is found in the
Saurashtra script or in the
Tamil script, but some are written with a reduced consonant form on the second consonant in the cluster, typically with ra and ya. Gemination is indicated with the Arabic shadda, while nasalization is indicated with an anusvara that is reminiscent of Devanagari in position but of
Telugu,
Kannada, or
Malayalam in shape. The nukta is composed of three dots, similar to the three dots found in modifying historically Arabic letters in the Persian script, and it is added to certain letters to form Arabic sounds. They can sometimes be ambiguous, with the nukta over the same letter sometimes mapping to multiple Arabic letters, as in
ja or as in
sa. Punctuation exists for marking word boundaries using colon-like marks, section boundaries using a combination of colon-like marks and double danda-like marks, and other Latin punctuation is also present. Abbreviation marks are represented by a small circle to the side, as is found in Modi and in
Goykanadi. Verse numbering is indicated by an overline and digits and number forms typically use those found throughout North India in the region. Some additional letters and forms have been found, are detailed in the Unicode Proposal, and are being researched. Over time some of the characters represented different sounds, which makes it difficult to read certain texts with the historical phonological values as compared to those with the modern phonological values known to most modern readers of published Ismaili literature. This is particularly true of the implosives, aspirants, and normal forms of
ba, da, and
ja, which shifted to render the implosive letter as a normal letter phonologically, the normal letter as an aspirant letter phonologically, and rendered the aspirant letter unnecessary. The implosive for
ja began to represent
za. == Sample text ==
