Unicode equivalence is the specification by the Unicode character encoding standard that some sequences of code points represent essentially the same character. This feature was introduced in the standard to allow compatibility with pre-existing standard character sets, which often included similar or identical characters.
Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
The default string primitive in Go, [50] Julia, Rust, Swift (since version 5), [51] and PyPy [52] uses UTF-8 internally in all cases. Python (since version 3.3) uses UTF-8 internally for Python C API extensions [53] [54] and sometimes for strings [53] [55] and a future version of Python is planned to store strings as UTF-8 by default.
Text normalization is the process of transforming text into a single canonical form that it might not have had before. Normalizing text before storing or processing it allows for separation of concerns, since input is guaranteed to be consistent before operations are performed on it.
In computer programming, a free-form language is a programming language in which the positioning of characters on the page in program text is insignificant. Program text does not need to be placed in specific columns as on old punched card systems, and frequently ends of lines are insignificant.
The Unicode Standard defines a codespace: [60] a sequence of integers called code points [61] in the range from 0 to 1 114 111, notated according to the standard as U+0000 – U+10FFFF. [62] The codespace is a systematic, architecture-independent representation of The Unicode Standard ; actual text is processed as binary data via one of several ...
The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...
UTF-32 (32-bit Unicode Transformation Format), sometimes called UCS-4, is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits (four bytes) per code point (but a number of leading bits must be zero as there are far fewer than 2 32 Unicode code points, needing actually only 21 bits).
