![]() Raises a LookupError in case the encoding cannot be found. Look up the codec for the given encoding and return its encoder function. These additional functions which use lookup() for the codec lookup: codecs. To simplify access to the various codec components, the module provides StreamWriter and StreamReader, respectively. Provide the interface defined by the base classes Stream writer and reader classes or factory functions. IncrementalEncoder and IncrementalDecoder, These have to provide the interface defined by the base classes Incremental encoder and decoder classes or factory functions. incrementalencoder ¶ incrementaldecoder ¶ The functions or methods are expected to work in a stateless mode. The encode() and decode() methods of Codec These must beįunctions or methods which have the same interface as The stateless encoding and decoding functions.

The module defines the following functions for encoding and decoding withĪny codec: codecs. Text encodings or with codecs that encode to Types, but some module features are restricted to be used specifically with Custom codecs may encode and decode between arbitrary Most standard codecsĪre text encodings, which encode text to bytes (andĭecode bytes to text), but there are also codecs provided that encode text to Manages the codec and error handling lookup process. This module defines base classes for standard Python codecs (encoders andĭecoders) and provides access to the internal Python codec registry, which GTK does not fully integrate with unicode objects.Codecs - Codec registry and base classes ¶ In GTK applications at all and only use UTF-8 encoded str objects since In general it is recommended to not use unicode objects Have to make sure that gettext will return UTF-8 encoded 8-bit strings for all ![]() This is especially important if you want to internationalize your Although we called _text() withĪ unicode instance as argument, _text() will always ![]() get_text () > type ( txt ), txt (, 'Fu\xc3\x9fb\xc3\xa4lle') > txt = unicode_string _main_:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal False set_text ( unicode_string ) > txt = label. Label () > unicode_string = u "Fu \u00df b \u00e4 lle" > label. > from gi.repository import Gtk > label = Gtk. UTF stands for “Unicode Transformation Format”, and the ‘8’ means that 8-bit One of the most commonly used encodings thatĪddresses this problem is UTF-8 (it can handle any Unicode code point). (Python raises a UnicodeEncodeError exception in thisĪlthough ASCII encoding is simple to apply it can only encode for 128 differentĬharacters which is hardly enough. If the code point is 128 or greater, the Unicode string can’t be represented If the code point is < 128, each byte is the same as the value of the code Of bytes, the Unicode string must be encoded. In order to convert this abstract representation into a sequence Basically, code points areĪs mentioned earlier, the representation of a string as a list of code points The Unicode standard describes how characters are represented by code points.įor example the characters above are represented with the code points ![]() Characters are abstract representations and their meaningĭepends on the language and context they are used in. Conceptually, a string is a list of characters such as ![]()
