Abstract
The ACE (ASCII Compatible Encoding) Design Team in IDN Working Group is selecting an appropriate ACE proposal. To push forward the work of ACE Design Team, this document illustrates the results of various ACEs that being applied to Chinese Domain Names.
1. Test data and tools
These test data were sampled from CNNIC's current registry database, with the total number of 100,000.
Applied ACEs are RACE-03 [RACE], BRACE-00 [BRACE], LACE-01 [LACE], UTF-6-00 [UTF6], DUDE-02 [DUDE], AMC-ACE-M-00 [AMCACEM], AltDUDE-01 [AltDUDE], AMC-ACE-O-00 [AMCACEO], AMC-ACE-R-01 [AMCACER], AMC-ACE-V-00 [AMCACEV], AMC-ACE-W-00 [AMCACEW], MACE-01 [MACE] and LDUDE-00[LDUDE].
2. Result of each ACE
HANZI_len is the characters in the Chinese string before UCS2-ACE coding, max_len is the maximum length that a ACE-coded string can reach, min_len is the minimum length that a ACE-coded string can reach, aver_len is the average length of all ACE-coded strings converted from the Chinese string with the same HANZI_len-size.
