ASCII: 128; 95 printable, 33 control

unicode: many
ASCII (American Standard Code for Information Interchange) is a character-encoding scheme that was standardised in 1963. There is no encoder required to create ASCII. Every machine supports it as standard, although some implement it via UNICODE. The only difference is in the number of bytes used to represent each character. The default is one byte per character yielding 128 standard encodings that map exactly with the first 128 characters in UNICODE encoding.
Extended ASCII is 8-bit encoding which is wider than standard ASCII and also includes all characters from standard ASCII encoding.ASCII is 7-bit, 128 possible values; Extended ASCII is 8-bit , 256 possible value;128 first characters of Extended ASCII is the same as ASCII, next 128 are additional. This why it is called Extended ASCII.What is ASCII?ASCII is mainly English language characters encoding, that is used for representation of text information.
128
ASCII stands for American Standard Code for Information Interchange. It provides a means to facilitate communication on computers. It has 128 characters.
American Standard Code for Information Interchange (ASCII )
First of all ASCII is encoding system that tells how binary data from file could be represented as text. Is was and still is very widely used starting 1960s. Standard ASCII encoding is 7-bits encoding allowing 128 values, while Extended ASCII is 8-bits encoding which allows 256 values, that is 128 more characters in the table. First 128 Extended ASCII table characters is the same as ASCII table, next 128 is additional characters.
ASCII is popular because of the way a computer's architecture works. A standard ASCII keyboard displays all letters of the alphabet, but that is not enough to conform to the 32bit standard. So other characters were implemented and invented, and assigned their own numerals in HEX and Binary.

1000
200 characters is 200 characters, unless you are talking about Unicode (which isn't Ascii).
A char is already an integer, so there is no conversion required. A character is simply an integer that maps to a glyph in the current code page. ASCII characters are 1 byte long and have a value in the range 0 to 127 while extended ASCII characters are in the 128 to 255 range. Wide characters (UTF16 UNICODE) characters are two bytes long and cover the range 0 to 65,535, where 0 to 127 map to the standard ASCII character set. UTF8 UNICODE characters are variable width (1 to 6 bytes in length), where 0 to 127 are single-byte characters mapping to the standard ASCII set.
If you're referring to kilobyte, then it contains 1024 bytes and if the characters are the standard ASCII character set where 1 character is 1 byte, then a kilobyte would have 1024 characters.
