Regex ?

[Theera]

Hi all,
Who is well known about Regex in B4A? Please explain me clearly?
Could I match Thaiword with mp3 File? I don't know about using pattern.

You can test whether all (or some) of the characters are Thai characters with Asc keyword. You should first find the Unicode values of Thai characters.

Please give me the example: IsThai(word) as boolean?

I don't know to use regex ? This is Thai unicode.
Please help me give example i.e. How to coding function IsThai(word) as boolean ?

P.S. Unicode Thai(UTF-8) is the same as Unicode Thai(UTF-8 without BOM)?

Best Regards

You do not need to use Regex for this. You should check the value returned from Asc(SomeCharacter) and see whether it is in the block of Thai characters.

Something like:

Sub IsThai(s As String) As Boolean
   For i = 0 To s.Length - 1
      Dim codePoint As Int = Asc(s.CharAt(i))
      If codePoint >= 0x0E00 AND codePoint <= 0x0E7F Then Return True
   Next
   Return False
End Sub

Can I use pattern with regex()?

Hi Erel,
I have ever seen Java using Pattern, Pattern="[ก-ฮ0-9ฯ-๙]*"
I don't know that Can I use pattern with regex()? If I can,then
if I define "เอาะ"="-oh" then "เกาะ"="Koh" too. How to coding?

P.S. "เกาะ" is mean "land"

See Regex tutorial: Regular expressions tutorial
It shouldn't be difficult to use this pattern.

Ask to learn more.

Hi Erel,
Is there a possibility or not that made error?,If I check many languages in your strategy post #4. I mean that data of langauges used in the same location between 0x0E00-0x0E7F.

Not sure what you mean. There is also no advantage of using Regex over the code I posted in post #4.
