How to compare two strings whether both are equal while ignoring the difference in special characters (example: ＆ vs & and many others)?

I attempted to compare two strings whether they are equal or not. They should return true if both are equal.

One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.

The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are ＆ and &

Is it due to different culture or language?
