Python 3.3 switched internal storage to use one of ISO-8859-1, UCS-2, or UTF-32 depending on the largest code point in the string. [30] Python 3.12 drops some functionality (for CPython extensions) to make it easier to migrate to UTF-8 for all strings. [31] Java originally used UCS-2, and added UTF-16 supplementary character support in J2SE 5.0.
International Components for Unicode (ICU) is an open-source project of mature C/C++ and Java libraries for Unicode support, software internationalization, and software globalization. ICU is widely portable to many operating systems and environments. It gives applications the same results on all platforms and between C, C++, and Java software.
Python versions up to 3.2 can be compiled to use them [clarification needed] instead of UTF-16; from version 3.3 onward, Unicode strings are stored in UTF-32 if there is at least 1 non-BMP character in the string, but with leading zero bytes optimized away "depending on the [code point] with the largest Unicode ordinal (1, 2, or 4 bytes)" to ...
Some programming languages, such as Seed7, use UTF-32 as an internal representation for strings and characters. Recent versions of the Python programming language (beginning with 2.2) may also be configured to use UTF-32 as the representation for Unicode strings, effectively disseminating such encoding in high-level coded software.
Converts Unicode character codes, always given in hexadecimal, to their UTF-8 or UTF-16 representation in upper-case hex or decimal. Can also reverse this for UTF-8. The UTF-16 form will accept and pass through unpaired surrogates e.g. {{#invoke:Unicode convert|getUTF8|D835}} → D835.
Rather, older 8-bit encodings such as ASCII or ISO-8859-1 are still used, forgoing Unicode support entirely, or UTF-8 is used for Unicode. [citation needed] One rare counter-example is the "strings" file introduced in Mac OS X 10.3 Panther, which is used by applications to lookup internationalized versions of messages. By default, this file is ...
This distinction has been deprecated since Python 3.3, which introduced a flexibly-sized UCS1/2/4 storage for strings and formally aliased Py_UNICODE to wchar_t. [8] Since Python 3.12 use of wchar_t, i.e. the Py_UNICODE typedef, for Python strings (wstr in implementation) has been dropped and still as before an "UTF-8 representation is created ...
Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...
