  2. Why IDN? • ASCII representation of Thai words is difficult to read/write • ใครกินไข่ไก่=> Kaikinkaikai / Kraikinkhaikai / … • ผู้ใหญ่บ้าน=> Pooyaiban / Poohyaibaan / … • No way of representing different words (different meaning) in Thai. • กฤษ, กฤต, กฤษณ์ => Krit

  3. TH Implementation • Fully compliant with IDN standard RFCs • RFC 3490, RFC 3491, RFC 3492 • Second-level domain name registration <Thai>.th • Support Languages: English and Thai (inclusion-based characters set)

  4. TH Language Table • Based on RFC2278 and Unicode 3.2 (U+0E01-U+0E5B) • Total Number of Codepoints allow for IDN: LDH + 82 (Thai Characters) • Consonants (Alphabet): 46 • Vowel: 18 • Tone marks: 4 • Sign: 4 • Number: 10 • No Variants preparations required • For more detail on Thai Language Table for IDN • http://www.iana.org/assignments/idn/registered.htm

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.
