_case 规则说明，以下列语句为例：
unicode.CaseRange{'A', 'Z', [unicode.MaxCase]rune{3, -3, 0}}
·其中 'A', 'Z' 表示此规则只影响 'A' 到 'Z' 之间的字符。
·其中 [unicode.MaxCase]rune 数组表示：
当使用 ToUpperSpecial 转换时，将字符的 Unicode 编码与第一个元素值（3）相加
当使用 ToLowerSpecial 转换时，将字符的 Unicode 编码与第二个元素值（-3）相加
当使用 ToTitleSpecial 转换时，将字符的 Unicode 编码与第三个元素值（0）相加
