- 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
- 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 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
- utf 8 - How to detect and fix incorrect character encoding - Stack Overflow
Bare ISO 8859-1 is almost guaranteed to be invalid UTF-8 Attempting to decode as ISO 8859-1 and then as UTF-8, and falling back to simply decoding as UTF-8 if this produces invalid byte sequences should work for this specific case In some more detail, the UTF-8 encoding severely restricts which non-ASCII character sequences are allowed
- 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
- 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
- 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)
