推荐答案

取决于您对什么是汉字的特定概念.也许您正在寻找 /p{Script=Hani}/，但如果我们想广泛使用，下面的正则表达式模式将匹配出现在中文写作中的内容.必要时加以限制.

Depends on your particular notion of what is a Chinese character. Perhaps you're looking for /p{Script=Hani}/, but if we want to cast our net wide, the following regex pattern will match stuff that occurs in Chinese writing. Restrict if necessary.

use 5.014;
/
    (?: p{Block=CJK_Compatibility}
    |   p{Block=CJK_Compatibility_Forms}
    |   p{Block=CJK_Compatibility_Ideographs}
    |   p{Block=CJK_Compatibility_Ideographs_Supplement}
    |   p{Block=CJK_Radicals_Supplement}
    |   p{Block=CJK_Strokes}
    |   p{Block=CJK_Symbols_And_Punctuation}
    |   p{Block=CJK_Unified_Ideographs}
    |   p{Block=CJK_Unified_Ideographs_Extension_A}
    |   p{Block=CJK_Unified_Ideographs_Extension_B}
    |   p{Block=CJK_Unified_Ideographs_Extension_C}
    )
/x;

是的，. 匹配一个字符.split DWYM 的空模式:

Yes, . matches one character. The empty pattern for split DWYM:

use utf8;
split //, '冰淇淋'
# returns ('冰', '淇', '淋')
