Line 19:

* The familiar Alt+### combination (where ### is from 0 to 255) retains the old [[MS-DOS]] behavior, i.e., generates characters from the legacy code pages now called "[[Windows code page#OEM code page|OEM code pages]]." For instance, the combination {{key press|Alt}}+{{key press|1}}{{key press|6}}{{key press|3}} would result in {{char|ú}} (Latin letter u with [[acute accent]]) which is at 163 in the OEM code page of CP437 or CP850.<ref name="WindowsAltAlgo" /> This did not work for characters not in the Windows Code Page (such as box-drawing characters).

* The new Alt+0### combination (which prefixes a zero to each Alt code), produces characters from the newer "[[Windows code page#ANSI code page|Windows code pages]]."{{efn|Microsoft initially referred to them as "ANSI" code pages, but later acknowledged that this as a misnomer.}} of the current active input language. For example, {{key press|Alt}}+{{key press|0}}{{key press|1}}{{key press|6}}{{key press|3}} yields the character {{char|£}} (symbol for the [[pound sterling]]) which is at 163 in CP1252.<ref name="WindowsAltAlgo">{{Cite web |date=2016-07-22 |title=To input characters that are not on your keyboard |url=http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/lang_char_code_input.mspx |url-status=dead |archive-url=https://web.archive.org/web/20160722031546/http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/lang_char_code_input.mspx?mfr=true |archive-date=2016-07-22 |access-date=2022-12-30 |website=Microsoft }}</ref>{{efn|But if the user has, for, example, Russian keyboard active, then the code page [[CP1251]] (Cyrillic) inis useused, where the symbol at codepoint 163 is [[Je (Cyrillic)]] (Ј), it is this and not £ that will be displayed.}}
