 Under Windows, the digit grouping symbol in many localisations (and
 international system) is the Unbrekable blank space (code UTF-8 is decimal
 160, hex 0xA0). Example : 200 000 000

 With french localisation, the function Int32ToLocaleSpecificString will
 generate a string with Unbreakble blank space for digit grouping symbol.
 The integer 200000000 will become the string "200 000 000"

                 [0]     50 '2'  char
                 [1]     48 '0'  char
                 [2]     48 '0'  char
                 [3]     -96 ' ' char
                 [4]     48 '0'  char
                 [5]     48 '0'  char
                 [6]     48 '0'  char
                 [7]     -96 ' ' char
                 [8]     48 '0'  char
                 [9]     48 '0'  char
                 [10]    48 '0'  char


 However, the function MgIsLegalUTF8 return False for the said string
 because the Unbrekable blank space caracter has a value of 0xA0 whitch is
 outside the one byte UTF-8 encoding for a caracter.

 https://www.fileformat.info/info/unicode/char/00a0/index.htm

 1-byte characters in UTF-8 are ASCII Characters 0-127.

 line of code in MgIsLegalUTF8
  case 1: if (*source >= 0x80 && *source < 0xC2) return false;
 (case 1 is for one byte UTF-8 encoding)
