Current Windows versions and all back to Windows XP and prior Windows NT (3.x, 4.0) are shipped with system libraries that support string encoding of two types: 16-bit "Unicode" (UTF-16 since Windows 2000) and a (sometimes multibyte) encoding called the "code page" (or incorrectly referred to as ANSI code page). 16-bit functions have names suffixed with 'W' (from "wide") such as SetWindowTextW.
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.
As Unicode included all the characters in the MSDOS code pages, this had the immediate benefit that all the old MSDOS Alt combinations worked, not just the ones that existed in the Windows Code Page. In the IBM PC Bios typing an Alt code greater than 255 produced the same as that number modulo 256. [ 3 ]
Unicode characters can then be entered by holding down Alt, and typing + on the numeric keypad, followed by the hexadecimal code, and then releasing Alt. [2] This may not work for 5-digit hexadecimal codes like U+1F937. Some versions of Windows may require the digits 0-9 to be typed on the numeric keypad or require NumLock to be on. [citation ...
The tool is usually useful for entering special characters. [1] It can be opened via the command-line interface or Run command dialog using the 'charmap' command.. The "Advanced view" check box can be used to inspect the character sets in a font according to different encodings (), including Unicode code ranges, to locate particular characters by their Unicode code point and to search for ...
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, [citation needed] although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used.
The following table shows Windows-1252. Differences from ISO-8859-1 have the Unicode code point number below the character, based on the Unicode.org mapping of Windows-1252 with "best fit". A tooltip, generally available only when one points to the immediate right of the character, shows the Unicode code point name and the decimal Alt code.
The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented writing systems are added.
