Having problems with message search?
Dear Hameed,
One way is to develop langauge tables
separately for each langauge, and then perhaps look at the whole picture in an
integrated way eventually for .af domain names.Â

Dear Dr Sarmad:
If we make a list
visually confusable characters within the script then there will be limitation
for certain languages those are yet to be developed and put in the technology
in case of first come first serve. Those languages will certain face the
problem of already reserved domain names. As you make have come through for
example Arabic character suwad duwad and many of the type and there
visual confusables in certain other languages. The exploitation of which can
cause security problems.
The other issue that
we dig of was the characters like Urdu DAAL and Pashto DAAL and certain others,
although visually they are slightly different but the usage, pronunciation and
concept is the same. The Afghans beyond the Durand line, know Pashto but don’t
know how to formally write Pashto and thus would not be able to differentiate
between Urdu and Pashto DAAL and certain other Characters unless they are
taught so.
Would you comment
please.
Best regards

Dear Hameed
There is no simple solution to this problem. I think a list of
confusables for all scripts is required to be generated then if a domain
name is registered using one of the confusable it can not be registered
with its counter part:
For example if there is already a www.apple.com
with cyrillic letter 'a' then one should not be allowed to registered www.apple.com with latin letter 'a'. This will
effectively solve the homoglyph problem at GTLD level.
Similarly a list of case fold and ligature normalization
confusables can be generated. For example one instance in this list can be
Ø¢
(Alef with maddah above U+0622) and ا+ٓ (Alef + maddah above; U+0627 + U+0653).
Both should be allowed at GTLD level but again FCFS (First come first serve)
policy should be implemented for instance if www.آج.org
is registered with 0622 then it can not be registered with 0627+0653. This
makes it a universal solution. These can not be normalized into a single
character because 0627+0653=622 in Urdu but not in Sindhi. This is not a
very convincing example but I am unable to think of another one right now.
At CCTLD level language table solution can be
implemented or perhapps we can have the same solution discussed above for the
sake of orthoganality.

Nadir

Dear Hameed,
That is precisely a problem which we need
to find a solution for. One "easy" solution is to have a script
centric language(?)-table. However, if that is allowed, it enables users
to type different similar-looking characters (0649 vs. 06cc) which can cause
security problems.
However, if language-table is truly
LANGUAGE table, then multiple languages will share the character set.
Latter could be the preferred solution. In this case if multiple
languages use the same URL, then it would be first-come-first-served (which is
what the model is currently, in any case). Thus, if you register www.kabulbank.com then I
cannot get it afterwards.
I am cc:ing others who can also
comment/advise on this, e.g. Ram has experience from Indian langauges
which share similar script/langauge challenges.

Dear Dr Sarmad:
What about a domain name that appears to be with
the same characters in Urdu Persian Arabic and Pashto i.e www.kabulbank.com . Do we
have any reservations in this.
Thank you.
