Split() doesn't work on 64Bit

I have an old 32Bit application. Now I want to make a 64Bit version, but split() doesn’t work correct.

Const langMonate As String =
English: January,February,March,April,May,June,July,August,September,October,November,December
German: Januar,Februar,Mrz,April,Mai,Juni,Juli,August,September,Oktober,November,Dezember
French: Janvier,Fvrier,Mars,Avril,Mai,Juin,Juillet,Aot,Septembre,Octobre,Novembre,Dcembre

PopUpMenuMonat
Sub Open()
dim Mon() as string
Mon = split(langMonate, “,”)
me.AddRows Mon
End Sub

This is the result as 32Bit application:

And this as 64Bit application:

It seems that the German umlauts are the problem, but only in 64Bit. In French language there is no problem with special characters.

It’s a known issue
Using a text object in the new framework should fix this.
