* Rules for ISCII to Unicode converter
* ISCII is a stateful encoding. To convert ISCII bytes to Unicode,
* which is both precomposed and decomposed from characters
* pre-context and post-context need to be considered.
*
* Post context
* i) ATR : Attribute code is used to declare the font and script switching.
* Currently we only switch scripts and font codes consumed without generating an error
* ii) EXT : Extention code is used to declare switching to Sanskrit and for obscure,
* obsolete characters
* Pre context
* i) Halant: if preceeded by a halant then it is a explicit halant
* ii) Nukta:
* a) if preceeded by a halant then it is a soft halant
* b) if preceeded by specific consonants and the ligatures have pre-composed
* characters in Unicode then convert to pre-composed characters
* iii) Danda: If Danda is preceeded by a Danda then convert to Double Danda
