[BRLTTY] General clarification on Writiing DOTs to device based on the string length

[Siju Samuel]

Hi,

While writing a string to a device using bral_apis_write,  how do we know
the actual length of the 'translated dot string". For example if the
braille display device length is 14  and want to write a line with 14 alpha
numeric characters. The corresponding dot translation might be more than 14
'dots' length (for example, to denote a number it might be using two dot).
 So do there have any api to know what position  of a string corresponds to
the translated dot position of a string and send the input to writeApi
accordingly?  How this is generally done ( to use brailapi)?  thanks in
advance for any input.

Thanks,
siju samuel
