The ASCII coding scheme is sufficient for
English and Western European languages but
is not large enough for Asian and other languages
that use different alphabets. Unicode is
a 16-bit coding scheme that has the capacity
of representing more than 65,000 characters
and symbols. The Unicode coding scheme is
capable of representing almost all the world’s
current written languages, as well as classic
and historical languages. To allow for expansion,
Unicode reserves 30,000 codes for future
