119 * Function Encoding::toUTF8
120 *
121 * This function leaves UTF8 characters alone, while converting almost all non-UTF8 to UTF8.
122 *
123 * It assumes that the encoding of the original string is either Windows-1252 or ISO 8859-1.
124 *
125 * It may fail to convert characters to UTF-8 if they fall into one of these scenarios:
126 *
127 * 1) when any of these characters: ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß
128 * are followed by any of these: ("group B")
129 * ¡¢£¤¥¦§¨©ª«¬­®¯°±²³´µ¶•¸¹º»¼½¾¿
130 * For example: %ABREPRESENT%C9%BB. «REPRESENTÉ»
131 * The "«" (%AB) character will be converted, but the "É" followed by "»" (%C9%BB)
132 * is also a valid unicode character, and will be left unchanged.
133 *
134 * 2) when any of these: àáâãäåæçèéêëìíîï are followed by TWO chars from group B,
135 * 3) when any of these: ðñòó are followed by THREE chars from group B.
136 *
137 * @name toUTF8
138 * @param string $text Any string.
