[idn] Arabic and REORDERING

["Soobok Lee" <lsb@postel.co.kr>]

This posting is to explain how REORDERING can help countries using even non-CJK scripts.

This is an arabic ML.com of length 34 :

REORDERING+AMC-Z: mgBKMSFCEFDBXAFHEQHNKCECCAFHDBBIDBBC   ( 36 )



This is another arabic label of length 55 which is constructed by
concatenating two arabic labels of length 34 and 21:

U+0627 U+0644 U+0625 U+0645 U+0627 U+0631 U+0627 U+062A
U+0627 U+0644 U+062F U+0648 U+0644 U+064A U+0629 U+0644
U+0644 U+0627 U+0633 U+062A U+0634 U+0627 U+0631 U+0627
U+062A U+0627 U+0644 U+0642 U+0627 U+0646 U+0648 U+0646
U+064A U+0629
U+0636 U+0645 U+064A U+0631 U+0627 U+0644 U+0645 U+062A
U+0643 U+0644 U+0645 U+0627 U+0644 U+0645 U+0636 U+0627
U+0641 U+0625 U+0644 U+064A U+0647

AMC-Z :           kgBAEBAAAAAAAAAAWFJDCE8GuBIF5B1A5DE43AuA1BHGBBAJGCBEEZDDC7AA2EMR1GsADQ     ( 69 > 59 = 63 - 4 : error!)

REORDERING+AMC-Z: lgBABCWPKSHQLCKLDBD7AAMHLOACAHHIQKDJCECCAFKDBEDDBBIDBBCJGD   ( 58 )
[ 58 / 53 = 1.094, close to the ratio for latin labels  in bare AMC-Z (1.09),
  compensation succeeded!  ]


Yet another arabic label of length :  47

U+0627 U+0644 U+0625 U+0645 U+0627 U+0631 U+0627 U+062A
U+0627 U+0644 U+062F U+0648 U+0644 U+064A U+0629 U+0644

AMC-Z :           kgBDBAAAAAAAAATFHDCE8FrBIF1BzA1DyT7ADGBBAJGCBEZDD4AA2ER7ESD (  58 )

REORDERING+AMC-Z: lgBBPQQIHCGHDBDZAIHHOACDHILKDGECCAFKDBBDBBIDBBCJG   ( 49 )


These experiments on two  arabic samples shows that
the maximum length of arabic labels for bare AMC-Z
is about 47, while that for REORDERING+AMC-Z is 55  with some errors of 1~2 characters.

With REORDERING, arabic-using people will have less complaints about
their imposed disadvantage in arabic ACE labels.
