How to remove acute accents from string in java?

I know about this

public static String stripAccents(String s) {
    s = Normalizer.normalize(s, Normalizer.Form.NFD);
    s = s.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");
    return s;
}

but it works not the way I want. It changes the sense of text

stripAccents("йод,ëлка,wäre") //иод,елка,ware

I want to delete only acute accents

stripAccents("café") //cafe

Just for the acute accents:

s = Normalizer.normalize(s, Normalizer.Form.NFD); // Decompose
s = s.replace("\u0301", ""); // Combining acute accent (´)
s = Normalizer.normalize(s, Normalizer.Form.NFC); // Compose again

Composing being the shortest, and often better represented in fonts.

This removes the zero length acute accents, even without regex.

For Italian cafè, accent grave, use \u0300.

It seems that it's better to just remap the specific set of accented characters with acute accent into plain letters:

public static String stripAccents(String s) {
   
    if (null == s || s.isEmpty()) {
        return s;
    }
    
    final String[] map = {
        "ÁÉÍÓÚÝáéíóúý",
        "AEIOUYaeiouy"
    };
    
    return s.chars()
            .mapToObj(c -> (char)(map[0].indexOf(c) > -1 ? map[1].charAt(map[0].indexOf(c)) : c))
            .collect(Collector.of(
                StringBuilder::new, StringBuilder::append, 
                StringBuilder::append, StringBuilder::toString
            ));
}

// or using updated switch statement in JDK 12
public static String stripAcuteAccents(String s) {
    if (null == s || s.isEmpty()) {
        return s;
    }
    char[] raw = s.toCharArray();
    for (int i = 0; i < raw.length; i++) {
        raw[i] = switch(raw[i]) {
            case 'Á' -> 'A'; case 'É' -> 'E'; case 'Í' -> 'I';
            case 'Ó' -> 'O'; case 'Ú' -> 'U'; case 'Ý' -> 'Y'; 
            case 'á' -> 'a'; case 'é' -> 'e'; case 'í' -> 'i';
            case 'ó' -> 'o'; case 'ú' -> 'u'; case 'ý' -> 'y';
            default -> raw[i];
        };
    }
    return new String(raw);
}

Basic tests:

String[] tests = {"café", "Á Toi", "ÁÉÍÓÚÝáéíóúý - bcdef"};
   
Arrays.stream(tests)
      .forEach(s -> System.out.printf("%s -> %s%n", s, stripAccents(s)));

output

café -> cafe
Á Toi -> A Toi
ÁÉÍÓÚÝáéíóúý - bcdef -> AEIOUYaeiouy - bcdef
