With Unicode you can program and accomplish many funny, cool and useful programs and tools as for instance, Abjad Calculator calculating the numerical value of letters derived from the Arabic alphabet through the use of the Abjad writing system, Bubble Text Generator to write letters in circle, Flip Text Generator to write letters upside down, Google Transliteration to convert English names to Persian/Arabic, etc.

3. Character Sets
» ASCII
˃ The 128 most commonly-used characters are each
represented by a sequence of 7 bits known as the
character’s ASCII code.
˃ The characters include letters, digits, punctuation
marks, and nonprintable control characters such as
the backspace, tab, carriage return, etc.
» Unicode
˃ The Unicode standard defines underlying numeric
values for a huge set of 65,536 characters.

5. What is Abjad ?
» Every letter in the
Arabic alphabet has a
numerical
(Gematrical) value.
» A number of
calculations can be
made from this basis.
» These are referred to
as numerological
(Abjad) calculations.

32. Tips
Simple String Methods
» charAt()
˃ The charAt(index) method returns the character at a specific index in
the string.
˃ The first character of a string is at index 0, the next at index 1, and so
on.
˃ The index argument must be greater than or equal to 0, and less than
the length of the string buffer.
» replaceAll()
˃ The String class also contains the replaceAll method for replacing and
splitting strings
˃ The replaceAll method replaces all matching substring.
