Use indexOf(char) and lastIndexOf(char) rather than String versions
An indexOf or lastIndexOf call with a single letter String can be
made more performant by switching to a call with a char argument.
Found with SonarLint.
As a side-effect of this change, we no longer need to suppress the
NON-NLS warnings.
