Hello, sorry for the delay.

I took the hint by Vijay again too literally.
Please see new version below, I added now helpers using matching codepage for iso8859-1.

[Bernhard Übelacker (＠bernhardu)]

Hello, sorry for the delay.

I rebased the patch to wine-9.16.

And added helpers to use instead the better matching codepage 28591 for iso8859-1.
