The original IBM PC code page 437 character set included a couple of characters ⌠ and ⌡ (codes 244 and 245 respectively) to build the integral symbol. These were deprecated in subsequent MS-DOS code pages , but they still remain in Unicode ( U+2320 and U+2321 respectively) for compatibility.
It is used in the mapping of some IBM encodings for Korean, such as IBM code page 933, which allows the use of the Shift Out and Shift In characters to shift to a double-byte character set. [5] Since the double-byte character set could contain compatibility jamo, halfwidth variants are needed to provide round-trip compatibility. [6] [7]
The visual weight of the first "2" matches the other characters better. (The top typeface is Adobe Garamond Pro; the size of the subscript is about 62% of the original characters, dropped below the baseline by about 16%. The second typeface is Myriad Pro; the superscript is about 60% of the original characters, raised by about 44% above the ...
Alchemical Symbols is a Unicode block containing symbols for chemicals and substances used in ancient and medieval alchemy texts. Many of the symbols are duplicates or redundant with previous characters. [3] Few fonts support more than a few characters in this block as of 2021. One that does and is free for personal use is Symbola 14.0.
In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content. [1] In particular some fonts display the character as a fixed-width blank.
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF. U+25A0–U+25CF. 25A0 25B0 25C0 ... Official Unicode Consortium code chart ...
ISO 3166-1 alpha-2 – two-letter country codes which are also used to create the ISO 3166-2 country subdivision codes and the Internet country code top-level domains. ISO 3166-1 alpha-3 – three-letter country codes which may allow a better visual association between the codes and the country names than the 3166-1 alpha-2 codes.
The Symbol font displays the character without any vinculum whatsoever; the overline may be a separate character at 0x60. [13] The JIS, [14] Wansung [15] and CNS 11643 [11] [16] code charts include a short overline attached to the radical symbol, whereas the GB 2312 [17] and GB 18030 charts do not. [18]
