\diameter produces a diameter symbol. What is the equivalent in ConTeXt?
⌀ or \varnothing Have a look at char-def.lua for a list of context names for various glyphs. It might make sense to enable the fonts.missing tracker. Then ConTeXt warns you that a particular glyph is not available. \enabletrackers [fonts.missing]
Is there any compilation of symbols avaliable in ConTeXt?
Not that I'm aware of. In ConTeXt you have easy access to all characters of any font¹. Either input the character directly if it's present in the current font or you can create a symbol: \definefontsynonym [minion] [name:minionproregular] \definesymbol [leaf] [\getnamedglyphdirect {minion} {bullet.010}] \starttext Foo \symbol[leaf] Bar \stoptext Marco ¹ http://tex.stackexchange.com/a/87563/5245
