There is a better font if you need only symbols, choose the "Unicode Symbols" link on the following page.
I'm trying to use Unicode.otf from http://users.teilar.gr/~g1951d I just copied it into texmf/fonts/opentype/unicodesymbols/Unicode.otf run luatools --generate and test %%%test0012.tex \definefont[WhatEver][Unicode] \starttext \WhatEver Hello \stoptext with texmfstart texexec --luatex test0012.tex Result: !luaTeX error (file /opt/texlive/ContextMKiv/tex/texmf/fonts/opentype/public/unicodesymbols/Unicode.otf): can't find table `CFF ' ==> Fatal error occurred, no output PDF file produced! (I'm using This is LuaTeX, Version snapshot-0.20.2-2007121721 (Web2C 7.5.6) ConTeXt ver: 2008.01.02 14:18 MKIV fmt: 2008.1.10 int: english/english ) Hence, I saved Unicode.otf as UnicodeSymbols.otf with fontforge (saved as Opentype CFF) %%%test0012.tex \definefont[WhatEver][UnicodeSymbol at 100pt] \starttext \WhatEver Hello \stoptext now works . Do I have make some mistake ? And How can I quicky access symbols like U+25c9 ? -- luigi it's new . it's powerful . it's luatex . http://www.luatex.org
