what is the difference between utf-16 and utf-8?
607899
Utf-8 and utf-16 both handle the same Unicode characters. They are both variable length encodings that require up to 32 bits per character. The difference is that Utf-8 encodes the common characters including English and numbers using 8-bits. Utf-16 uses at least 16-bits for every character.

The utf8_bin collation compares strings based purely on their Unicode code point values. ... utf8_general_ci applies Unicode normalization using language-specific rules and compares strings case-insensitively.

The \xef\xbb\xbf is a Byte Order Mark for UTF-8 - the \x is an escape sequence indicating the next two characters are a hex sequence representing the character code. The \n is a new line character. To remove this, you can use rstrip() .

The Difference Between Unicode and UTF-8 Unicode is a character set. UTF-8 is encoding. Unicode is a list of characters with unique decimal numbers (code points). ... Encoding translates numbers into binary.

A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes). A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits.

In Python 3, Bytes literals are always prefixed with 'b' or 'B'; they produce an instance of the bytes type instead of the str type. They may only contain ASCII characters; bytes with a numeric value of 128 or greater must be expressed with escapes.

Short answer: In UTF-8, a BOM is encoded as the bytes EF BB BF at the beginning of the file. ... The character U+FFFE is permanently unassigned so that its presence can be used to detect the wrong byte order. UTF-8 has the same byte order regardless of platform endianness, so a byte order mark isn't needed.

Use UTF-8 which is backwards compatible with ANSI (Windows-1252). These are character sets which let the browser know how to display webpages correctly. Webpages are default encoded with UTF-8 and Windows-1252 was from before that was the case. Since it is on all Windows it is still supported by all browsers as well.

contentType is the type of data you're sending, so application/json; charset=utf-8 is a common one, as is application/x-www-form-urlencoded; charset=UTF-8 , which is the default. dataType is what you're expecting back from the server: json , html , text , etc.

ASCII, ISCII and Unicode are encoding languages with unique characteristics that define their usage. ASCII uses a 7-bit encoding and ISCII uses an 8-bit which is an extension of ASCII while Unicode is a variable bit encoding that doesn't fit into one 8 bit and generally uses 16-bit encoding.

It is an efficient encoding of Unicode documents that use mostly US-ASCII characters because it represents each character in the range U+0000 through U+007F as a single octet. UTF-8 is the default encoding for XML and since 2010 has become the dominant character set on the Web.

UTF-16 encoding is a variable byte encoding scheme which uses either 2 bytes or 4 bytes to represent unicode code points. Most of the characters for all modern languages are represented using 2 bytes. The latin alphabet ñ with code point U+00F1 and with binary value 11110001 is represented in UTF-16 encoding as.

There is a new format in the save dialog CSV UTF-8 (Comma delimited) which is distinct from Comma Separated Values which is also still in there. ... CSV to the casual observer seems a simple portable format, but its looks are deceiving. If the data is pure ASCII (bytes 0-127) you'll be fine.
