 # **American Standard Code for Information Interchange** (ASCII)
 
-ASCII  abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices ([Binary](../../science/math/Binary%20System.md) to Text). Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are printable characters, which severely limited its scope. Modern computer systems have evolved to use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set.

 Without getting into the low-level details of each of these encodings, there are really only two options useful for modern usage:
 
-- If the content is encoded in the same encoding as the enclosing [JSON](../files/JSON.md) document (which for practical purposes, is almost always UTF-8), leave `contentEncoding` unspecified, and include the content in a string as-is. This includes text-based content types, such as `text/html` or `application/xml`.

 - If the content is binary data, set `contentEncoding` to `base64` and encode the contents using [Base64](https://tools.ietf.org/html/rfc4648). This would include many image types, such as `image/png` or audio types, such as `audio/mpeg`.
