Issues with recent utf8 patch

[Rafał Mużyło]

First, I appologize: I missed the post stating that editor is not
working. I decided to check slang, too.
New issue:
a strange crash (screen type independant)
I searched for 'enable-charset' in mc sources. Several results were
found. I chose one and pressed F3. mc ran out of memory and was killed
by the system.
And configuration dialog displays fine with slang.
