CoachASCII uses only 7-bit encoding and hence it does not support any other language rather than American English. Unicode separates the concepts of code point, code unit and glyph, allowing for a code set that can support a majority of the world's languages. Unicode also supports a number of different encoding algorithms and code unit to code point translations, making it much more powerful but more complex to use.
Most software and communication programs understand ASCII. Not all software and communication programs understand Unicode. Even when a program supports Unicode, it may not be able to fully utilize it due to a lack of support for a given encoding, or a lack of the proper glyphs to display a string's contents.

What does Java use instead of ASCII?
ASCII and Java are 2 totally different things. ASCII is a naming convention where a certain letter, number, or punctuation mark is a specific keyboard code (Carriage Return, CR, is code 31, Line Feed 14, Capital A 96). Java is a programming language that handles text in multiple formats as needed, Unicode, EBDIC, ASCII. The two are not intertwined.
What is the HTML code for an asterisk?
It depends. In Unicode, its U+002A. If the page is in ASCII, then is 0x2A. But you shouldn't need an HTML entity. You should be about to just type it in *
What is the purpose of ASCII?
The American Standard Code for Information Interchange was made to standardize 128 numeric codes that represent the English letters, Symbols, and Numbers. Any USA keyboard is made with this standard in mind.
Which encoder creates ASCII?
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.
Why do need Unicode when you have Ascii?
ASCII only has 127 standard character codes and only supports the English alphabet. While you can use the extended ASCII character to provide a set of 256 characters and thus support other languages there's no guarantee that other systems will use the same code page, so the characters will not display correctly across all systems (the characters you see will depend upon which code page is currently in use). Moreover, some languages, particularly Chinese, have thousands of symbols that simply cannot be encoded in ASCII. UNICODE encoding supports all languages and the first 127 symbols are also the same as ASCII, so all characters appear the same across all systems. UTF8 is the most common UNICODE encoding in use today because it uses one-byte per character for the first 127 characters and is therefore fully compliant with non-extended ASCII. If the most-significant bit is set then the character is represented by 2 or more bytes, the combination of which maps to the UNICODE encoding.
