What are ASCII and Non-ASCII characters?

In computer languages, all characters are represented by numbers. The letters and number used on an English appearing keyboard are in a range of numbers from 32 up to 127 and are called ASCII characters. Characters represented by number from 128 to 254, which include the special letters used in foreign languages, are called non-ASCII characters, or multibyte characters. Microsoft recommends using only ASCII characters for the name of a computer, user, folder, or file. In Vista and Windows 7, using a non-ASCII character in the name of a computer, can cause problems.
