Explicitly set aspell encoding 

xml-copy-editor doesn't explicitly set aspell's "encoding" config option
to "utf-8" (which is, as far as I can tell, the actual encoding
of string data passed to aspell_speller_check() function), so if
the option is set to a different value in aspell configuration file
or via ASPELL_CONF environment variable, it may lead to a crash.
