System.Text.Encoding.GetEncoding("iso-8859-1") throws PlatformNotSupportedException?

[Andreas Huber]

Hi

See subject. This happens on the emulators that ship with Windows Mobile 6
Professional SDK as well as on my English HTC Touch Pro (all .NET CF 3.5).
iso-8859-1 stands for Western European (ISO), which is probably the most
important encoding besides us-ascii (at least when one goes by the number of
usenet posts).

I'm having a hard time to understand why this encoding is not supported,
while the following ones are supported (again on both the emulators & my
HTC):

iso-8859-2 (Central European (ISO))
iso-8859-3 (Latin 3 (ISO))
iso-8859-4 (Baltic (ISO))
iso-8859-5 (Cyrillic (ISO))
iso-8859-7 (Greek (ISO))

So, is support for say Greek more important than support for German, French
and Spanish?
Can anyone shed some light on this?

Thanks!
