Android Question Determination for Unicode cherecters

[Imran_Farooq]

Hi, want to determine that a string have Unicode character or not. Please help me.

I thought strings in Android were always Unicode, in which case this will do it:

Dim StringHaveUnicodeCharacterFlag As Boolean = (TestString.Length <> 0)

but more likely you are trying to determine if a string contains a particular character or substring, in which case the .Contains string function might do the job:

If PlayerName.Contains("oo") Then
    Score = HighScore + 10    'or whatever you want to do when the player's name has lowercase double-o in it
End If

or are you trying to find out if the string contains any non-ASCII characters, ie characters that need specific character maps or multiple bytes to encode?

eg "Nineteen characters" will generally encode to 19 bytes but "15 characters ?" will be longer than 15 bytes because the "smiling face with halo" character is Chr(128519) which is going to need at least three bytes to represent it, because a single byte can only hold 256 different values, usually 0..255 for oldtimers, or -128 to 127 for newbies.

There is no such thing. All characters are unicode characters.
