how can I convert unicode string to ASCII in java
提问by PPShein
I'm now trying to convert unicode font to ascii in android. I wrote following coding to convert unicode font to ascii but it's failed. Because result cannot display properly after being converted.
我现在正在尝试将 unicode 字体转换为 android 中的 ascii。我编写了以下代码将 unicode 字体转换为 ascii，但失败了。因为转换后结果无法正常显示。
unicode font = '??????????????' to something like '\u100F\u1039\u100D'
unicode 字体 = '????????????????' 类似于 '\u100F\u1039\u100D'
public static String toJAVA (String zawgyi) {
String output = "";
char[] charArray = zawgyi.toCharArray();
for (int i = 0; i < charArray.length; i++) {
char a = charArray[i];
if ((int) a > 255) {
output += "\u" + Integer.toHexString((int) a) + "--";
} else {
output += a;
}
}
return output;
}

use java.text.Normalizer class to convert from unicode to ascii. here is a sample code from the answer https://stackoverflow.com/a/2097224/931982
使用 java.text.Normalizer 类将 unicode 转换为 ascii。这是答案https://stackoverflow.com/a/2097224/931982 中的示例代码
String s = "口水雞 hello ?";
String s1 = Normalizer.normalize(s, Normalizer.Form.NFKD);
String regex = Pattern.quote("[\p{InCombiningDiacriticalMarks}\p{IsLm}\p{IsSk}]+");
String s2 = new String(s1.replaceAll(regex, "").getBytes("ascii"), "ascii");
System.out.println(s2);
System.out.println(s.length() == s2.length());
