替换字符串中的非 ASCII 字符

问题描述

我有字符串 A função, Ãugent 在其中我需要替换像 ç,ã 这样的字符，Ã 带有空字符串.

I have strings A função, Ãugent in which I need to replace character like ç,ã,Ã with empty strings.

如何只匹配那些非 ASCII 字符?

How can I match only those non ASCII characters?

我正在使用一个函数

public static String matchAndReplaceNonEnglishChar(String tmpsrcdta) {
    String newsrcdta = null;
    char array[] = Arrays.stringToCharArray(tmpsrcdta);
    if (array == null)
        return newsrcdta;

    for (int i = 0; i < array.length; i++) {
        int nVal = (int) array[i];
        boolean bISO =
                // Is character ISO control
                Character.isISOControl(array[i]);
        boolean bIgnorable =
                // Is Ignorable identifier
                Character.isIdentifierIgnorable(array[i]);
        // Remove tab and other unwanted characters..
        if (nVal == 9 || bISO || bIgnorable)
            array[i] = ' ';
        else if (nVal > 255)
            array[i] = ' ';
    }
    newsrcdta = Arrays.charArrayToString(array);

    return newsrcdta;
}

但它不能正常工作......需要什么改进......这里我还有一个问题是最终字符串被空格字符替换，这在字符串中创建了额外的空间.

but it is not working properly..what improvement it is needed...here I have one more problem is that final string is getting replaced by space character which create the extra space in string.

推荐答案

这将搜索并替换所有非 ASCII 字母:

This will search and replace all non ASCII letters:

String resultString = subjectString.replaceAll("[^\x00-\x7F]", "");
