Android Question [Solved] How do remove emoticons characters from a string?

asales · Jun 18, 2019

I see the code to remove accents from a string
https://www.b4x.com/android/forum/threads/remove-accents-from-string.40429/#content

I have strings with emoticons, like this example:
Have fun!!

Good luck!

Happy birthday!

Do you want a beer??

Have a nice day! Give my money$$!!

Is possible to remove all the emoticons (

and others) from the string and left only the texts?

Thanks in advance for any tip.

it depends on how they are added. if they all use something like [smile] or :smile: it's easy.

if it is a mix of things you probably need to use a loop with replacement parameters to use with regex.replace

It is not so simple because these characters are not contained in a single range.

If you are only interested in ASCII characters:

B4X:

Dim sb As StringBuilder
sb.Initialize
For i = 0 to s.Length - 1
 Dim c As String = s.CharAt(i)
 If Asc(c) < 128 Then sb.Append(c)
Next
Return sb.ToString

Thanks. Works fine.
I just change the decimal number to 256 to include accents in the string.

B4X:

Sub RemoveEmojis(s As String) As String
    Dim sb As StringBuilder
    sb.Initialize
    For i = 0 To s.Length - 1
        Dim c As String = s.CharAt(i)
        If Asc(c) < 256 Then sb.Append(c)
    Next
    Return sb.ToString
End Sub
