Fixes #485

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Automated Testing

See tests in SummaryReturnExampleTest.kt, for example, SummaryReturnExampleTest.testCompareChar().
UTBot generated these names before the fix:

        "testCompareChars_NLessThan1"
        "testCompareChars_0OfCharactertoCharsiEqualsA" // need to change i -> I, to -> To
        "testCompareChars_0OfCharactertoCharsiEqualsB" // need to change i -> I, to -> To
        "testCompareChars_0OfCharactertoCharsiNotEqualsB" // need to change i -> I, to ->To

And these names after the fix:

       "testCompareChars_NLessThan1"
       "testCompareChars_0OfCharacterToCharsIEqualsA"
       "testCompareChars_0OfCharacterToCharsIEqualsB"
       "testCompareChars_0OfCharacterToCharsINotEqualsB"
