39. What about other languages?

40. Thai.

41. Thai input is based on E.161

43. ช-ฌ
ก-ฉ ญ-ฐ
ฒ-ณ บ-ผ
ต-น
ว-ส
ฝ-ภ
ม-ล
ห-ฮ vowels and special characters.

44. ช-ฌ
ก-ฉ ญ-ฐ
44 base characters.
22 vowels.
ฒ-ณ บ-ผ 4 tone marks.
ต-น
ว-ส
ฝ-ภ
ม-ล
ห-ฮ vowels and special characters.

45. T9 for Thai doesn’t help all
the time.

46. And I think this happens to
most of South East Asia
languages as well.
