  • What are Unicode, UTF-8, and UTF-16? - Stack Overflow
    Encoding basics Note: If you know how UTF-8 and UTF-16 are encoded, skip to the next section for practical applications UTF-8: For the standard ASCII (0-127) characters, the UTF-8 codes are identical This makes UTF-8 ideal if backwards compatibility is required with existing ASCII text Other characters require anywhere from 2-4 bytes
  • unicode - UTF-8, UTF-16, and UTF-32 - Stack Overflow
    UTF-8 is the de-facto standard in most modern software for saved files More specifically, it's the most widely used encoding for HTML and configuration and translation files (Minecraft, for example, doesn't accept any other encoding for all its text information) UTF-32 is fast for internal memory representation, and UTF-16 is kind of deprecated, currently used only in Win32 for historical
  • What is the difference between UTF-8 and Unicode?
    The main difference between UTF-8, UTF-16, and UTF-32 character encodings is how many bytes they require to represent a character in memory: UTF-8 uses a minimum of 1 byte, but if the character is bigger, then it can use 2, 3 or 4 bytes
  • What is the difference between UTF-8 and ISO-8859-1 encodings?
    UTF-8 is a multibyte encoding that can represent any Unicode character ISO 8859-1 is a single-byte encoding that can represent the first 256 Unicode characters Both encode ASCII exactly the same way
  • Unicode, UTF, ASCII, ANSI format differences - Stack Overflow
    What is the difference between the Unicode, UTF8, UTF7, UTF16, UTF32, ASCII, and ANSI encodings? In what way are these helpful for programmers?
  • Unicode (UTF-8) reading and writing to files in Python
    The point of UTF-8 is to be able to encode 21-bit characters (Unicode) as an 8-bit data stream (because that's the only thing all computers in the world can handle) But since most OSs predate the Unicode era, they don't have suitable tools to attach the encoding information to files on the hard disk The next issue is the representation in Python
  • Whats the difference between UTF-8 and UTF-8 with BOM?
    1070 The UTF-8 BOM is a sequence of bytes at the start of a text stream (0xEF, 0xBB, 0xBF) that allows the reader to more reliably guess a file as being encoded in UTF-8 Normally, the BOM is used to signal the endianness of an encoding, but since endianness is irrelevant to UTF-8, the BOM is unnecessary
  • Using UTF-8 Encoding (CHCP 65001) in Command Prompt Windows . . .
    Note: This answer shows how to switch the character encoding in Windows consoles (terminals) to (BOM-less) UTF-8 system-wide (code page 65001), so that shells such as cmd exe and PowerShell properly encode and decode characters (text) when communicating with external (console) programs with full Unicode support, and in cmd exe also for file I O [1] If, by contrast, your concern is about the
  • Quais as principais diferenças entre Unicode, UTF, ASCII, ANSI?
    Quais são as principais diferenças entre os " encodings " Unicode, UTF, ASCII, ANSI? Todos eles são realmente encodings ou uns são apenas "sub-categorias" dos outros? Não pretendo saber todos os detalhes de cada um, apenas uma breve de cada e, se possível, como se diferenciam entre si
  • What does Content-type: application json; charset=utf-8 really mean?
    Content-type: application json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8
