All the characters used in email messages are ASCII characters and so are all the characters used in HTML documents. An ASCII file is a data or text file that contains only characters coded from the standard ASCII character set.

These codes, however, may not be the same in all computers and files containing these characters may not display or convert properly by another ASCII program.
