this is because the fall back of \aring is defined as 's', you can patch
enco-def: 

somewhere at the top:

\definecharacter textring          23

lower: 

\definecharacter Aring {\buildtextaccent\textring A}
\definecharacter aring {\buildtextaccent\textring a}
\definecharacter Uring {\buildtextaccent\textring U}
\definecharacter uring {\buildtextaccent\textring u}

this is indeed *input* mapping [or sometimes intermediate mapping]

Ok, so we need to add:  

\definecharacter Ntilde {\buildtextaccent\texttilde N}
\definecharacter ntilde {\buildtextaccent\texttilde n}

indeed, there is no good fall back defined, thanks for pointing it out

patch enco-def.tex and regenerate the formats

this version of context has named glyph definitions instead of the less
readable accent/commans ones; the internals are still the same, except from
some enoding-to-encoding expansion improvements, but i redid the defs and
for sure missed a couple of glyphs, btw, these issues are unrelated to
pdftex [except that unicode searching for eastern european languagesis now
smoother].
