[lldb] fix failing tests due to CI diagnostics rendering (#171685)

This patch fixes issues introduced by
#171491 when running tests in
CI.

The shell tests expect certain characters when matching diagnostics.
With #171491, those characters
can either be Unicode specific characters or their ASCII equivalent. The
tests were always expecting the ASCII version. This patch fixes this by
using a regex to match one or the other.
