There is a problem with the mapping of letter phi to Uni-\ncode. Prior to Unicode version 3.0, the difference between U+03C6,\nGREEK SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly\ndescribed; only the glyph shapes in the Unicode book could be used as a\nreference. Starting with Unicode 3.0, the reference glyphs have been\nexchanged and described verbally also: In mathematical context, U+03D5\nis the stroked variant and U+03C6 the curly glyph. Unfortunately, most\nfont vendors didn't update their fonts to this (incompatible) change in\nUnicode. At the time of this writing (January 2006), it is not clear\nyet whether the Adobe Glyph Names 'phi' and 'phi1' also change its\nmeaning if used for mathematics, thus compatibility problems are likely\nto happen - being conservative, groff currently assumes that 'phi' in a\nPostScript symbol font is the stroked version.\n\nIn groff, symbol '\\[*f]' always denotes the stroked version of phi, and\n'\\[+f]' the curly variant.\n\nA \\[*A] Alpha u0391 +\nB \\[*B] Beta u0392 +\n \\[*G] Gamma u0393 +\n \\[*D] Delta u0394 +\nE \\[*E] Epsilon u0395 +\nZ \\[*Z] Zeta u0396 +\nH \\[*Y] Eta u0397 +\n \\[*H] Theta u0398 +\nI \\[*I] Iota u0399 +\nK \\[*K] Kappa u039A +\n \\[*L] Lambda u039B +\nM \\[*M] Mu u039C +\nN \\[*N] Nu u039D +\n \\[*C] Xi u039E +\nO \\[*O] Omicron u039F +\n \\[*P] Pi u03A0 +\nP \\[*R] Rho u03A1 +\n \\[*S] Sigma u03A3 +\nT \\[*T] Tau u03A4 +\nY \\[*U] Upsilon u03A5 +\n \\[*F] Phi u03A6 +\nX \\[*X] Chi u03A7 +\n \\[*Q] Psi u03A8 +\n \\[*W] Omega u03A9 +\n \\[*a] alpha u03B1 +\n \\[*b] beta u03B2 +\n \\[*g] gamma u03B3 +\n\n \\[*d] delta u03B4 +\n \\[*e] epsilon u03B5 +\n \\[*z] zeta u03B6 +\n \\[*y] eta u03B7 +\n \\[*h] theta u03B8 +\n \\[*i] iota u03B9 +\n \\[*k] kappa u03BA +\n \\[*l] lambda u03BB +\n \\[*m] mu u03BC +\n \\[*n] nu u03BD +\n \\[*c] xi u03BE +\no \\[*o] omicron u03BF +\n \\[*p] pi u03C0 +\n \\[*r] rho u03C1 +\n \\[ts] sigma1 u03C2 terminal sigma +\n \\[*s] sigma u03C3 +\n \\[*t] tau u03C4 +\n \\[*u] upsilon u03C5 +\n \\[*f] phi u03D5 (stroked glyph) +\n \\[*x] chi u03C7 +\n \\[*q] psi u03C8 +\n \\[*w] omega u03C9 +\n \\[+h] theta1 u03D1 variant theta\n \\[+f] phi1 u03C6 variant phi (curly shape)\n \\[+p] omega1 u03D6 variant pi, looking like omega\n \\[+e] uni03F5 u03F5 variant epsilon\n\nCard symbols\n\nC \\[CL] club u2663 black club suit\nS \\[SP] spade u2660 black spade suit\nH \\[HE] heart u2665 black heart suit\n\\[u2661] uni2661 u2661 white heart suit\nD \\[DI] diamond u2666 black diamond suit\n\\[u2662] uni2662 u2662 white diamond suit\n\nAUTHORS\nThis document was written by James Clark , with addi-\ntions by Werner Lemberg and Bernd Warken\n, and revised to use real tables by Eric\nS.
