Represents a mutable string of characters 表示可變字符字符串。
If the alternate attribute is set to shifted , then these variable characters are of only minor importance 如果替代屬性設置為移位( s ) ,那么這些可變字符就是次要的。
The alternate attribute controls the handling of variable characters in the uca : white space , punctuation marks , and symbols 替代屬性控制對uca中的可變字符的處理:空白、標點和符號。
If the alternate attribute is set to non - ignorable , then differences among these variable characters are of the same importance as differences among non - variable characters , such as the english alphabets 如果替代屬性設置為不可忽略( n ) ,那么這些可變字符之間的差異與不可變字符(比如英語字母)之間的差異同樣重要。
If the alternate attribute is set to shifted and the strength attribute is set to the quaternary level , then variable characters are considered in a comparison when all other aspects of the strings - base letters , accents , and case - are identical 如果替代屬性設置為移位而且強度屬性設置為第四級,那么在字符串的所有其他方面(基本字母、重音和大小寫)都相同時,在比較中會考慮可變字符。
