Character Encoding

The subject of character encoding encompasses a wide range of important elements. Character encodings for beginners. A character encoding provides a key to unlock (ie. It is a set of mappings between the bytes in the computer and the characters in the character set.

Without the key, the data looks like garbage. Furthermore, the misleading term charset is often used to refer to what are in reality character encodings. Another key aspect involves, character Sets and Encodings.

Character encodings for beginners explains some of the basic concepts about character encodings, and why you should care. Character encodings: Essential concepts provides explanations of terminology such as Unicode, character sets, coded character sets, character encodings, the document character set, and character escapes. character encoding - Unicode, UTF, ASCII, ANSI format differences .... What is the difference between the Unicode, UTF8, UTF7, UTF16, UTF32, ASCII, and ANSI encodings?

In what way are these helpful for programmers? For more information about Unicode, see the Unicode Home Page, or read the tutorial An Introduction to Writing Systems & Unicode. It's important to note that, character sets, coded character sets, and encodings It is important to clearly distinguish between the concepts of a character set versus a character encoding.

encoding - What are Unicode, UTF-8, and UTF-16? Now a character encoding is needed to access this character set, and as the question asks, I will concentrate on UTF-8 and UTF-16. This perspective suggests that, memory considerations So how many bytes give access to what characters in these encodings? UTF-8: 1 byte: Standard ASCII 2 bytes: Arabic, Hebrew, most European scripts (most notably excluding Georgian) 3 bytes: BMP

What's the difference between encoding and charset?. A character-encoding scheme is a mapping between one or more coded character sets and a set of octet (eight-bit byte) sequences. UTF-8, UTF-16, ISO 2022, and EUC are examples of character-encoding schemes. From another angle, encoding - "’" showing on page instead of - Stack Overflow. This only forces the client which encoding to use to interpret and display the characters.

But the actual problem is that you're already sending the exact characters ’ (encoded in UTF-8) to the client instead of the character ’. The client is basically correctly displaying ’ using the UTF-8 encoding. What is character encoding and why should I bother with it. The main difference, is that this does not follow the Unicode character set, by contrast it uses some Chinese character set.

Decoding data When you encode your data, you use an encoding, but when you decode data, you will need to know what encoding was used, and use that same encoding to decode it. Declaring character encodings in HTML. A character encoding declaration is also needed to process non-ASCII characters entered by the user in forms, in URLs generated by scripts, and so forth.

This article describes how to do this for an HTML file.
