1Note that all \[charXXX] entity names have been removed from the font files. 2They don't make sense for Unicode. 3 4The following entity from the original troff manual (by Ossanna and 5Kernighan) is unmapped: 6 7 bs shaded solid ball (Bell System logo, AT&T logo) 8 9Character 0x002D has not been given a name because its Unicode name 10HYPHEN-MINUS is so ambiguous that it is unusable for serious typographic 11use. 12 13\[wp] has been mapped to 0x2118, because according to Unicode 4.1's 14NamesList.txt, U+2118 SCRIPT CAPITAL P is really a Weierstrass `p', 15neither SCRIPT not CAPITAL. 16 17The following line could be added; \[space] is known to devps but is not 18documented and not known to devdvi (actually, there is no space glyph within 19the TeX system). 20 21 space 24 0 0x0020 22 23devps maps \[a~] and `~' to `asciitilde', which is equivalent to 0x02DC, but 24this glyph is just too small. We map them to 0x007E instead. 25 26devps maps \[a^] and `^' to `circumflex', which is equivalent to 0x02C6, but 27this glyph is just too small. We map them to 0x005E instead. 28 29devps maps \[*U] to `Upsilon1', which is equivalent to 0x03D2. We map it to 300x03A5 instead. 31 32devps maps \[*W] to `Omega', which is equivalent to either 0x2126 or 0x03A9. 33We map it to 0x03A9. 34 35devps maps \[*D] to `Delta', which is equivalent to either 0x2206 or 0x0394. 36We map it to 0x0394. 37 38 39Adding Unicode characters 40------------------------- 41 42Assume you want to use a Unicode character not provided in the list, say 43U+20AC. You need to do two things: 44 45- Add a line 46 47 u20AC 24 0 0x20AC 48 49 (the second column is computed as 24 * wcwidth(0x20AC)) to the file 50 R.proto, or, when groff is already installed, to the four fonts files in 51 $(prefix)/share/groff/<version>/font/devutf8/. 52 53- In your source file, use the notation \[u20AC] to access it.
