Interaction between charset variables and alias definitions

[Dave Feustel <dfeustel@xxxxxxxxxxxxxx>]

I changed all mutt's charset variables from "utf-8" to
"utf-8:us-ascii:iso-8859-1" and then mutt reported IDN errors in all of
my alias definitions. The errors disappeared when I went back to just
"utf-8". What is the connection between charset and alias in mutt?

Thanks.
