There will be no problems if you ignore the locale and specify
&encoding explicitly. Tests in testdir are not *scripts*, they are
*input* (like -s command-line option, but actually invoked in rather
strange and indirect fashion), so you may simply use ^K there directly
like if you were typing. Otherwise use execute + normal.
