Anthony Howe noticed that gcc was complaining about ISO 8859-1 accented characters used in the two-level-tlds file. With his kind help, we converted those to equivalent IDN representation. Diffs are:
278c278 < aéroport.ci ---
xn--aroport-bya.ci
893c893 < drøbak.no ---
xn--drbak-wua.no
1955c1955 < lea?gaviika.no ---
xn--leagaviika-52b.no
2835c2835 < osterøy.no ---
xn--ostery-fya.no
3554c3554 < tysvær.no ---
xn--tysvr-vra.no
3587c3587 < unjárga.no ---
xn--unjrga-rta.no
3650c3650 < vegårshei.no ---
xn--vegrshei-c0a.no
As a practical matter this should have little operational impact since those domains are obscure and unlikely to be abused. Nonetheless, we thank Anthony for the correction.
