# This set of tests check the behavior of the IDNA options in "dig".
#
# "dig" supports two IDNA-related options:
#
# +[no]idnin - Translates a domain name into punycode format before sending
# the query to the server.
# +[no]idnout - Translates the received punycode domain names into appropriate
# unicode characters before displaying.
#
# The tests run "dig" against an authoritative server configured with a minimal
# root zone and nothing else. As a result, all queries will result in an
# NXDOMAIN. The server will return the qname sent, which "dig" will display
# according to the options selected. This returned string is compared with
# the qname originally sent.
#
# In the comments below, the following nomenclature (taken from RFC 5890) is
# used:
#
# A-label: Label comprising ASCII characters that starts xn-- and whose
# characters after the xn-- are a valid output of the Punycode
# algorithm.
#
# Fake A-label: An A-label whose characters after the xn-- are not valid
# Punycode output.
#
# U-label: Unicode (native character) form of a label.
#
# For the purpose of this test script, U-labels do not include labels that
# comprise purely ASCII characters, which are referred to as "ASCII-labels"
# here. Valid ASCII-labels comprise letters, digits and hyphens and do not
# start with a hyphen.
#

# Tests of transitional processing of a valid U-label
#
# IDNA2003 introduced national character sets but, unfortunately, didn't
# support several characters properly. One of those was the German character
# "ß" (the "Eszett" or "sharp s"), which was interpreted as "ss". So the
# domain “faß.de” domain (for example) was processed as “fass.de”.
#
# This was corrected in IDNA2008, although some vendors that adopted this
# standard chose to keep the existing IDNA2003 translation for this character
# to prevent problems (e.g. people visiting www.faß.example would, under
# IDNA2003, go to www.fass.example but under IDNA2008 would end up at
# www.fa\195\159.example - a different web site).
#
# BIND has adopted a hard transition, so this test checks that the transitional
# mapping is not used. The tests are essentially the same as for the valid
# U-label.
