Happy Birthday in Thai

[nazdrug]

I want to write "Happy Birthday" in Thai for a friend's birthday card.

How do you write, "Happy Birthday" in Thai?

Thanks in advance ^_^

[TK]

Happy Birthday = ÊØ¢ÊѹµìÇѹà¡Ô´

However, it is better to add "polite" particles at the end, so ...
If you are male, say/write ÊØ¢ÊѹµìÇѹà¡Ô´¹Ð¤ÃѺ
If you are female say/write ÊØ¢ÊѹµìÇѹà¡Ô´¹Ð¤Ð

The answer TK gave is the Thai way to say "Happy Birthday", it is pronunced "Sook Sun Wan Goed".

But you can also write "Happy Birthday" in Thai Script, that would be
