What version of iconv -l is that produces such a list? That in glibc 2.3.4 does not produce the header when redirected.
I have version '2.3.2.ds1-20' on Debian testing. '--silent' doesn't help.
I found an old RH9 system that did the same thing.
Your fix is not safe: iconv in libiconv produces items separated by space or newline. Looks like we will have to work harder to distinguish the two.
Can anything with a lowercase letter be safely rejected? That would bring the spurious names down to 2 (FROM and TO).
No. I think what we can do is to look to see if most lines end in //, and if so assume glibc format.

which leads to

A possible fix seems to be to replace
ext <- readLines(icfile)
by
ext <- grep("/$", readLines(icfile), value = TRUE)
but I don't know if that's guaranteed to work.
