replace any non-ascii character in a string in java
提问by leba-lev
How would one convert -lrb-300-rrb- 922-6590to -lrb-300-rrb- 922-6590in java?
在java中如何转换-lrb-300-rrb-┬á922-6590为-lrb-300-rrb- 922-6590？
Have tried the following:
尝试了以下方法：
t.lemma = lemma.replaceAll("\p{C}", " ");
t.lemma = lemma.replaceAll("[\u0000-\u001f]", " ");
Am probably missing something conceptual. Will appreciate any pointers to the solution.
我可能缺少一些概念性的东西。将不胜感激任何指向解决方案的指针。
Thank you
谢谢

Try the next:
尝试下一个：
str = str.replaceAll("[^\\p{ASCII}]", " ");
str = str.replaceAll("[^\\p{ASCII}]", " ");
By the way, \p{ASCII}is all ASCII: [\x00-\x7F].
顺便说一句，\p{ASCII}是所有ASCII： [\x00-\x7F]。
In ahother hand, you need to use a constant of Patternfor avoid recompiled the expression every time.
另一方面，您需要使用常量Pattern以避免每次都重新编译表达式。
private static final Pattern REGEX_PATTERN =
Pattern.compile("[^\p{ASCII}]");
public static void main(String[] args) {
String input = "-lrb-300-rrb- 922-6590";
System.out.println(
REGEX_PATTERN.matcher(input).replaceAll(" ")
); // prints "-lrb-300-rrb- 922-6590"
}

Assuming you only want to keep a-zA-Z0-9and punctuation characters, you could do:
假设你只想保留a-zA-Z0-9和标点符号，你可以这样做：
t.lemma = lemma.replaceAll("[^\p{Punct}\w]", " "));
