This patch fixes issues introduced by 
https://github.com/llvm/llvm-project/pull/171491 when running tests in CI.

The shell tests expect certain characters when matching diagnostics. With 
https://github.com/llvm/llvm-project/pull/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.
