Normalize a character/string to remove accents. (For comparison)

normalizeChar.mjs

/*
Two things will happen here:
1) normalize()ing to NFD Unicode normal form decomposes combined graphemes into the combination of simple ones. The è of Crème ends up expressed as e + ̀.
2) Using a regex character class to match the U+0300 → U+036F range, it is now trivial to globally get rid of the diacritics, which the Unicode standard conveniently groups as the Combining Diacritical Marks Unicode block.
