Can anybody explain the use of the three American English braille tables, en-us-comp6.ctb, en-us-comp8.ctb, and en-us-compbrl.ctb? I looked at the table, it looks to me that only the en-us-comp6.ctb has entries defining 8 dot compuer braille for upper case letters. The same table also has "comp6 A 456-1" entry. In this case, what will upper case A be translated into, one cell with dot patter 17, or two cells with pattern "456-1"? In other words, what table should I use if I want 6-dot US computer braille, and what table is for 8-dot US computer braille?


Thanks,
