You can use brlapi_writeDots(), which requires an ISO-11548-1 byte array. I guess the 16bit encoding used by liblouis is unicode U+28YZ encoding? You thus simply need to truncate the 16bit value 0x28YZ into the 8bit value 0xYZ. > After reading a string from this (till encounter spaces or enter ) , can the > the output from it be directly used in lou_backTranslateString() as input? I haven't tried it, but AIUI, liblouis should be able to handle input with something like this, yes. You should probably ask the liblouis list about that.
