1.CharMatcher的field 类型
ANY：匹配任意字符。
NONE：任何字符都不匹配
WHITESPACE：匹配字符里面的空格。
BREAKING_WHITESPACE：匹配字符之间是否被空格隔断。
INVISIBLE：确定字符是否不可见，不可见的字符包括：SPACE_SEPARATOR, LINE_SEPARATOR, PARAGRAPH_SEPARATOR,
CONTROL, FORMAT, SURROGATE, 和PRIVATE_USE
DIGIT： Determines whether a character is a digit according to Unicode. If you only care to match ASCII digits,
you can use inRange(‘0‘, ‘9‘).
JAVA_LETTER：Determines whether a character is a letter according to Java‘s definition. If you only care to
match letters of the Latin alphabet, you can use inRange(‘a‘, ‘z‘).or(inRange(‘A‘, ‘Z‘))。
JAVA_DIGIT：Determines whether a character is a digit according to Java‘s definition. If you only care to match
ASCII digits, you can use inRange(‘0‘, ‘9‘)。
JAVA_LETTER_OR_DIGIT ：
Determines whether a character is a letter or digit according to Java‘s
definition.
JAVA_ISO_CONTROL ：Determines whether a character is an ISO control character as specified
JAVA_LOWER_CASE：
Determines whether a character is lower case according to Java‘s
definition.
JAVA_UPPER_CASE ：Determines whether a character is upper case according to Java‘s definition.
ASCII：Determines whether a character is ASCII, meaning that its code point is less than 128.
SINGLE_WIDTH：Determines whether a character is single-width (not double-width). When in doubt,
this matcher errs on the side of returning false (that is, it tends to assume a character is double-width).
