Unicode allows 17 "planes" of 2^16 characters. Thus, Unicode characters range from U+0000 to U+10FFFF - a total of 17 * 2^16 or 1,114,112 code points. As of Unicode 5.0.0, 102,012 actual characters have been assigned to code points.
Upper case U in ASCII/Unicode is binary 0101011, U is code number 85. Lower case u in ASCII/Unicode is binary 01110101, u is code number 117.

EBCIDIC (Extended BCD Interchange Code)Unicode
In computer memory, character are represented using predefined character set. Historically 7 bit American Standard Code for Information Interchange (ASCII) code, 8 bit American National Standards Institute (ANSI) code and Extended Binary Coded Decimal Interchange Code(EBCDIC) were used. These coding scheme represents selected characters into 7 or 8 bit binary code. These character schemes do not represent all the characters in all the languages in uniform format. At present Unicode is used to represent characters into the computer memory. Unicode provides universal and efficient character presentations and hence evolved as modern character representation scheme. Unicode scheme is maintained by a non-profit organization called Unicode consortium. Unicode is also compatible with other coding scheme like ASCII. Unicode use either 16 bits or 32 bits to represent a character. Unicode has capability represent characters from all the major languages in use currently across the world.
The ASCII code for the letter D is 68 in decimal, 0x44 in hexadecimal/Unicode.
ASCII, EBCDIC and Unicode
Range. ASCII has only 128 characters (95 visible, 33 control), UniCode has many-many thousands. Note: UniCode includes ASCII (first 128 characters), and ISO-8859-1 (first 256 characters). (From these you can deduct that ISO-8859-1 also includes ASCII.)
The square root symbol is Unicode 0x221A. To show it, you either need to draw it graphically, or you need to have a Unicode representation library.
Morse code is a digital signal.
