I think it might be from deep in the fog of this code-porting war:

' Function to get a Thai comparison string
Private Sub GetThaiComparisonString(s As String) As String
'''Dim chars() As Char = s.ToCharArray
Dim chars(s.Length) As Char
For I = 0 To s.Length - 1
    chars(I) = s.CharAt(I)
Next

It's obvious in the light of day, but at the time we were like in a swamp with alligators up our arses...

an alternate way using JavaObject library

B4X:

    Dim a As String =  "A string with words"
    Dim b() As Char = a.As(JavaObject).RunMethod("toCharArray",Null)

Lol where the heck is the documentation about doing that magic trick? What other secret methods and incantations are available? Does it work on other types, like Ints, Floats, Arrays, Lists?

In particular, I vaguely remember seeing some Array slicing and dicing operations that looked pretty useful, assuming I can remember them when I need them...

@emexes
the inverse

B4X:

    Dim a As String =  "A string with words"
    Dim b() As Char = a.As(JavaObject).RunMethod("toCharArray",Null)
    Dim d As String 
    d =  d.As(JavaObject).RunMethod("valueOf",Array(b))
    Log(d)

@emexes: maybe we need to glue byteconverter lib to your arse for handy reference bc.ToChars( s as string) as Char() plus many other useful conversions

?

B4X:

    Dim s As String = "A string with words"
    Dim a() As String = Regex.Split("", s)
   
    For Each n As Char In a
        Log(n)
    Next

Only words

B4X:

    Dim s As String = "A string with words"
    Dim a() As String = Regex.Split("[^a-zA-Z]", s)
    
    For Each n2 As String In a
        Log(n2)
    Next

True.

If the function naming was more consistent, then I'd probably remember even without the handy reference.
