char's ARE ALWAYS unsigned. :-)

Also I've found out, that MASK1 is superfluous, because on implicit converting from char to int all upper bits are automaticlly 0.

No, all upper bits are the value of the sign bit, you can remove the mask only if

you use unsigned values.

So we can code instead:

char c = c2bMap.charAt(c2bMapIndex[current >> SHIFT] + (current & MASK));

          char c = (current < '\u0100') ? c2bMap.charAt(current) :

c2bMap.charAt(c2bMapIndex[current >> SHIFT] + (current & MASK));
