Well, your piece works well if "display character set" is set to
ASCII; it ASCIIzes as expected.  But it fails in the trivial case, when
"display character set" is UTF-8; then the fallback branch is taken :)

I normally have "UTF-8" for the display character set in my cfg; but
it doesn't work.

That's my report.  BTW, the usual ASCIIzation of the esperantic
letters in Latin-3 (and Unicode) is by adding x for the hat or breve;
so that the usual test phrase which contains all the accented letters
of Esperanto,

Eĥoŝanĝo ĉiuĵaŭde       (i.e. "Echo change on every Thursday")

becomes

Ehxosxangxo cxiujxauxde

(the letter x is not a member of Esperanto alphabet, and besides, x is
at the end of the alphabet, so that the ASCIIzed words sort well).
Lynx simply drops the hats (Ehosango ciujaude), kaj "ŝanĝo" (change)
becomes "sango" (blood)  ;)
