c#: String normalization explanation

U+1E09 = LATIN SMALL LETTER C WITH CEDILLA AND ACUTE
U+0033 = DIGIT THREE
U+2044 = FRACTION SLASH
U+0034 = DIGIT FOUR

note:
FormC: Compose the decomposed e.g: \u0033\u2044\u0034 => U+00BE or ¾

FormD: keeps the string without performning any normalizaation;

FormKC: U+1E09 is already nomalized so, when you use FormD it will decompose it and normalize any decomposed that follows it
    e.g: U+1E09 will be decomposed to \u0063\u0327\u0301
    and  \u0033\u2044\u0034 will be composed to U+00BE

FormKD: Decompose eveything U+1E09 => \u0063\u0327\u0301 and keeps \u0033\u2044\u0034 as it's (already decomposed form)


NOTE: the character will still be displayed the same in most case... it may change though
when ¾ is decompsed it changes to 3/4
