John, no, it is not a misspelling, thats a pronunciation indication for Hindi
consonants. when a character is considered half, the vowel sound does not come
with it. But braille reader knows that a character is halfed if dot 4 preceeds
the character. I also forgot to add in my last e-mail that always keyword works
in 2 senarios. First when the character is defined with sign keyword and second
when always is used with before classname.
