  • encoding - What are Unicode, UTF-8, and UTF-16? - Stack Overflow
    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
    Unicode is a standard and about UTF-x you can think as a technical implementation for some practical purposes: UTF-8 - "size optimized": best suited for Latin character based data (or ASCII), it takes only 1 byte per character but the size grows accordingly symbol variety (and in worst case could grow up to 6 bytes per character)
  • What is the difference between UTF-8 and Unicode?
    UTF-16 can not take 3 bytes, it can either take 2 or 4 bytes UTF-16 is not compatible with the ASCII table UTF-32 always uses 4 bytes Remember: UTF-8 and UTF-16 are variable-length encodings, where UTF-8 can take 1 to 4 bytes, while UTF-16 will can take either 2 or 4 bytes UTF-32 is a fixed-width encoding, it always takes 32 bits
  • What is the difference between UTF-8 and ISO-8859-1 encodings?
    UTF UTF is a family of multi-byte encoding schemes that can represent Unicode code points which can be representative of up to 2^31 [roughly 2 billion] characters UTF-8 is a flexible encoding system that uses between 1 and 4 bytes to represent the first 2^21 [roughly 2 million] code points
  • Unicode, UTF, ASCII, ANSI format differences - Stack Overflow
    On Windows and Java, this often means UTF-16; in many other places, it means UTF-8 Properly, Unicode refers to the abstract character set itself, not to any particular encoding UTF-16: 2 bytes per "code unit" This is the native format of strings in NET, and generally in Windows and Java
  • Quais as principais diferenças entre Unicode, UTF, ASCII, ANSI?
    O tamanho do UTF-8 e UTF-16 é variável, o primeiro de 1 à 4 bytes (dependendo da versão poderia ir até 6 bytes, mas na prática não acontece) e o segundo é 2 ou 4 bytes O UTF-32 tem sempre 4 bytes Há uma comparação entre eles Não sei o quanto é preciso Certamente não é completo Unicode
  • python - UnicodeDecodeError: utf8 codec cant decode byte 0xa5 in . . .
    Under Encoding tab, select the option Unicode (UTF-8) from Save this document as drop-down list; Save the file; Using Notepad: Open csv file using notepad; Navigate to File > Save As option; Next, select the location to the file; Select the Save as type option as All Files( ) Specify the file name with csv extension; From Encoding drop-down
  • Whats the difference between UTF-8 and UTF-8 with BOM?
    UTF-8 can be auto-detected better by contents than by BOM The method is simple: try to read the file (or a string) as UTF-8 and if that succeeds, assume that the data is UTF-8 Otherwise assume that it is CP1252 (or some other 8 bit encoding) Any non-UTF-8 eight bit encoding will almost certainly contain sequences that are not permitted by UTF-8
  • pandas - How to solve UnicodeDecodeError: utf-8 codec cant decode . . .
    The question in the OP is about decoding the content of the file UnicodeDecodeError: 'utf-8' codec can't decode byte, while this answer is for SyntaxError: 'unicodeescape' Two completely different issues
  • utf-8 codec cant decode byte 0xa0 in position 4276: invalid start byte
    If the input has a stray '\xa0', then it's not in UTF-8, full stop Yes, you have to either recode it to UTF-8 (see: iconv, recode commands, or a lot of text editors and IDEs can do it), or read it using an 8-bit encoding (as all the other answers suggest)
