What is ASCII encoding scheme?
ASCII. American Standard Code for Information Interchange (ASCII) is a character-encoding scheme and it was the first character encoding standard. It is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127.
Does UTF-8 include ASCII?
UTF-8 is backward-compatible with ASCII and can represent any standard Unicode character. The first 128 UTF-8 characters precisely match the first 128 ASCII characters (numbered 0-127), meaning that existing ASCII text is already valid UTF-8. All other characters use two to four bytes.
What is non ASCII text?
Non-ASCII characters are those that are not encoded in ASCII, such as Unicode, EBCDIC, etc. ASCII is limited to 128 characters and was initially developed for the English language.
How many non-ASCII characters are there?

What is an ASCII text?

Is ASCII valid UTF-8?
Why isn’t ASCII encoding included in the UTF-8 standard?
ASCII encoding isn’t included because it is not necessary. UTF-8 is the same as ASCII, the MSB is irrelevant in text streams. You should be able to get a correct textual representation using the UTF8 encoding, as long as the content was sent and received properly.
How do I choose the ASCII encoding for my App?
When selecting the ASCII encoding for your app, consider the following: The ASCII encoding is usually appropriate for protocols that require ASCII. If you require 8-bit encoding (which is sometimes incorrectly referred to as “ASCII”), the UTF-8 encoding is recommended over the ASCII encoding.
What is the ASCII character limit for Unicode characters?
Because ASCII is a 7-bit encoding, ASCII characters are limited to the lowest 128 Unicode characters, from U+0000 to U+007F. If you use the default encoder returned by the Encoding.ASCII property or the ASCIIEncoding constructor, characters outside that range are replaced with a question mark (?) before the encoding operation is performed.
What does encoding default mean on Windows Phone?
Encoding.Default refers to the system-default ANSI code-page in regular windows, inherited from the depths of time. Even on regular windows, it is not a good idea to use Encoding.Default. No such concept exists on windows phone, so : use the correct encoding; which usually means .UTF8.
