判断当前文本是否包含中文
issue：此方法只能判断部分CJK字符（CJK统一汉字）
public boolean isChineseWord(String str) {
Pattern p = Pattern.compile("[\u4e00-\u9fa5]");
Matcher m = p.matcher(str);
return m.matches();
}
issue:完美判断是否包含中文方法(根据Unicode编码完美的判断中文汉字和符号)
private static boolean isChinese(char c) {
Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS ||
ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS||
ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A ||
ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B||
ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION ||
ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS||
ub == Character.UnicodeBlock.GENERAL_PUNCTUATION) {
return true;
}
return false;
}
