-# Chromium: Drop all the stringprep files including RFC 3491 for IDNA 2003.
-# ICU supports UTS 46 (IDNA2003, transition, and IDNA 2008), but Chromium
-# does not use IDNA 2003 any more and uses transitional/IDNA 2008 for which
-# a separate resource (uts46.nrm) is used. Therefore, we can drop rfc3491 as
-# well.
-# If we ever need to support other stringprep (e.g. LDAP, XMPP, SASL),
-# we have to add back the corresponding prep files.
