How to remove diacritics in Perl 6


How to remove diacritics in Perl 6

I hope this helps . Perl 6 has great Unicode processing support in the Str class. To do what you are asking in (1), you can use the samemark method/routine.
Per the documentation:
code :
multi sub samemark(Str:D $string, Str:D $pattern --> Str:D)
method    samemark(Str:D: Str:D $pattern --> Str:D)
say 'åäö'.samemark('aäo');                        # OUTPUT: «aäo␤» 
say 'åäö'.samemark('a');                          # OUTPUT: «aao␤» 

say samemark('Pêrl', 'a');                        # OUTPUT: «Perl␤» 
say samemark('aöä', '');                          # OUTPUT: «aöä␤» 
say "p̄".ords;                  # OUTPUT: «(112 772)␤»
.uniname.say for "p̄".ords;     # OUTPUT: «LATIN SMALL LETTER P␤COMBINING MACRON␤»
.say for "p̄".uninames;         # OUTPUT: «LATIN SMALL LETTER P␤COMBINING MACRON␤»
say "p̄".codes;                 # OUTPUT: «2␤»
say "p̄".chars;                 # OUTPUT: «1␤»

I think the issue was by ths following , You can use the libraries described in Text normalization in Go.
Here's an application of those libraries:
code :
// Example derived from: http://blog.golang.org/normalization

package main

import (
    "fmt"
    "unicode"

    "golang.org/x/text/transform"
    "golang.org/x/text/unicode/norm"
)

func isMn(r rune) bool {
    return unicode.Is(unicode.Mn, r) // Mn: nonspacing marks
}

func main() {
    t := transform.Chain(norm.NFD, transform.RemoveFunc(isMn), norm.NFC)
    result, _, _ := transform.String(t, "žůžo")
    fmt.Println(result)
}

Does that help sed doesn't work on Unicode codepoints, it works on bytes so when it is given p̄ it sees 0x<0070 0304> whereas Perl 6 properly sees it as one grapheme, and treats it as such. Which means s/p/a/ would do absolutely nothing as p doesn't match p̄.
You could have tried s:ignoremark/p/a/ (:m) which would have given you a,

wish of those help I'm trying to remove Hebrew diacritics. I need to remove all diacritics, except for given diacritics, coming after given letters. , Your RemoveDiacritics method should look like
code :
public static string RemoveDiacritics(Dictionary<char, char[]> exclude, string source)
{
    string exclusionGroup = string.Join("|", exclude.Select(p => string.Concat(p.Key, string.Join(string.Empty, p.Value))));
    string leaveOnly = String.Concat(String.Format(@"({0})|\p{{M}}+", exclusionGroup));
    return Regex.Replace(source, leaveOnly, "$1");
}

like below fixes the issue I tried this on a windows box, it works.
I think though that the file has to open in its correct encoding.

wish help you to fix your issue I think you mean Redirect and not Rewrite given that Rewrite would mean that the URL stays the same, and you display the intended content (which I think is what you don't want).
The strategy that I think you want, can be implemented by creating a custom route constraint that matches everything that has an any special chars on it.
