So maybe this a TeXLive documentation issue: Where should users put 
their OpenType fonts if they are in .ttf/.ttc format and not .otf?

I've checked it, but "luatoots --find-file euler.otf" doesn't find it.

It does find xits-math.otf and asana-math.otf in the texmf-dist tree, 
but it doesn't find cambria.ttc and euler.otf in the texmf-local tree.
Nevertheless, context could use cambria.ttc but couldn't find euler.otf.

As I've checked, euler.otf is also listed in the luatex-cache files
of my texmf-local tree.

$ luatools --find-file euler.otf
LuaTools | fileio: loading 'files' for '/opt/texlive/texmf-local' from 

$ grep euler.otf 

$ grep -2 euler.otf 


Something strange seems to be going on here!

Yes, I've also seen this bug before.  Maybe it would be better
not to ship two different versions of the same font in TeXLive.
