encoding - What are Unicode, UTF-8, and UTF-16? - Stack Overflow An encoding form maps a code point to a code unit sequence A code unit is the way you want characters to be organized in memory, 8-bit units, 16-bit units and so on UTF-8 uses one to four units of eight bits, and UTF-16 uses one or two units of 16 bits, to cover the entire Unicode of 21 bits maximum
Character encodings for beginners - World Wide Web Consortium (W3C) This Unicode encoding is a good choice because you can use a single character encoding to handle any character you are likely to need This greatly simplifies things This greatly simplifies things Using Unicode throughout your system also removes the need to track and convert between various character encodings
What is character encoding and why should I bother with it But still in many cases applications just have to assume or guess what encoding they should use (e g they use the standard encoding of the operating system) There still is a lack of awareness about this, as still many developers don't even know what an encoding is Mime types Mime types are sometimes confused with encodings
Choosing applying a character encoding - World Wide Web Consortium (W3C) The x-user-defined encoding is a single-byte encoding whose lower half is ASCII and whose upper half is mapped into the Unicode Private Use Area (PUA) Like the PUA in general, using this encoding on the public Internet is best avoided because it damages interoperability and long-term use
encoding - ’ showing on page instead of - Stack Overflow You have a mismatch in your character encoding; your string is encoded in one encoding (UTF-8) and whatever is interpreting this page is using another (say ASCII) Always specify your encoding in your http headers and make sure this matches your framework's definition of encoding Sample http header: Content-Type text html; charset=utf-8
Handling character encodings in HTML and CSS (tutorial) In this context, that key is called a character encoding There are many character encodings to choose from Choosing applying a character encoding offers simple advice on which character encoding to use for your content, and how to apply it How to declare a character encoding You should always specify the encoding used for an HTML or XML page
urlencode - What is %2C in a URL? - Stack Overflow You should use your language's URL encoding methods when placing strings in URLs You can see a handy list of characters with man ascii It has this compact diagram available for mapping hexadecimal codes to the character:
How do I correct the character encoding of a file? Firefox will detect the encoding - you can see what it came up with under View -> Character Encoding I changed my file's encoding using TextMate once I knew the correct encoding File -> Reopen using encoding and choose your encoding Then File -> Save As and change the encoding to UTF-8 and line endings to LF (or whatever you want)
Difference between encoding and encryption - Stack Overflow Encoding transforms data into another format using a scheme that is publicly available so that it can easily be reversed Encryption transforms data into another format in such a way that only specific individual(s) can reverse the transformation For Summary - Encoding is for maintaining data usability and uses schemes that are publicly available
Tutorial: Character Encoding and Unicode - World Wide Web Consortium (W3C) The search for the best encoding always to some extent was in conflict with the need to use a common encoding that met many needs, even if somewhat incompletely A brief history of character encoding is provided in Richard Gillam, Unicode Demystified, pp 25-59 More and More Characters 5-bit encodings; 6-bit encodings
