Why IDN?

• ASCII representation of Thai words is difficult
  to read/write
• ???????????? gt Kaikinkaikai / Kraikinkhaikai /
  
• ??????????? gt Pooyaiban / Poohyaibaan /
• No way of representing different words (different
  meaning) in Thai.
• ???, ???, ????? gt Krit

Thai domain name issues

• Naming in Thai generally use long words (more
  characters required)
• ASCII name not longer than 63
• Thai Maximum characters that can be used as a
  domain name is about 30-45. (Depends on naming)
• In Thai abbreviation is not a common. Except
  government related words.
• Spelling English word in Thai can be variant.
• ACE is not human readable. More difficult to edit
  Zone file.
