The RDD this function will be used on contains unicode strings. This test uses default type strings, causing implementations of removePunctuation that use string.translate() to pass this test. However string.translate() does not behave well for unicode strings, which cause cryptic errors later down the line (4c). Aditionally positive test results for 4b wil confuse students debugging errors at 4c. Changing the testcases to unicode strings better guides students towards using the regular expressions (re) module.

The RDD the student specified 'removePunctuation()' function will be used on contains unicode strings.
This test (4b) used default type strings, causing implementations of removePunctuation that use '.translate()' to pass this test.
However '.translate()' does not behave well for unicode strings, which cause cryptic errors later down the line (4c).
Aditionally positive test results for 4b wil confuse students debugging errors at 4c.
Changing the testcases to unicode strings better guides students towards using the regular expressions (re) module for answering question 4b.
