The Windows Code Page 1252 was an extension of ISO/IEC 8859-1 (8859 Part 1 or "ISO Latin-1") standard, so it had the degree sign at the same code point, 0xB0. The code point in the older DOS Code Page 437 was 0xF8 (248 decimal); therefore, the Alt code used to enter the symbol directly from the keyboard is Alt+ 248.
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases.
Unicode input is method to add a specific Unicode character to a computer file; it is a common way to input characters not directly supported by a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive ...
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 pages." [a] For example, Alt+ 0 1 6 3 yields the character £ (symbol for the pound sterling) which is at 163 in CP1252. [2] [b]
Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use. Important messages could be signalled by striking the bell on the teletype. This was carried over on PCs by generating a buzz sound. 4 Line feed is used for "end of line" in text files on Unix / Linux systems.
The hyphen-minus (keyboard hyphen), en dash, em dash, and mathematical minus/negative symbols are different (see WP:Manual of Style/Dashes). Pressing the -on your keyboard, usually next to the 0 (zero) key, will produce a hyphen-minus. Methods of producing the other characters are described below.
On computers with Windows XP or Windows 7 (or similar), digits on the numeric keypad can be pressed with the Alt key held then released: Numeric keypad: Alt+0 1 5 0 for en dash "–" or Alt+0 1 5 1 for em dash "—". [2] On computers using Apple keyboards , the Option key can be used with hyphen key:
The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1]
