ruby - 按键排序散列，忽略重音

Question

我有一个像这样的散列:

dict = { 
  "someKey"        => [ ... ],
  "anotherKey"     => [ ... ],
  "yetAnōtherKéy"  => [ ... ]
}

我想通过对原始哈希进行排序来获得新的哈希。排序应该忽略重音(通过将重音字符替换为非重音版本来完成)，

replacements = [
    ["ā", "a"], ["á", "a"], ["à", "a"], ["ǎ", "a"],
    ["ō", "o"], ["ó", "o"], ["ò", "o"], ["ǒ", "o"],
    ["ī", "i"], ["í", "i"], ["ì", "i"], ["ǐ", "i"],     
    ["ē", "e"], ["é", "e"], ["è", "e"], ["ě", "e"],
    ["ū", "u"], ["ú", "u"], ["ù", "u"], ["ǔ", "u"]
]

但是生成的散列中的键应该保留原始键。这怎么可能？

我试过了

dict = Hash[dict.sort_by{|k,v| k}]

这有效并且确实对散列进行了排序。但是，它不会忽略重音，即以重音字符开头的单词会排到底部。

另一种尝试是:

replacements.each {|replacement| z.gsub!(replacement[0], replacement[1])}

根据 Cary Swoveland 的评论更正了代码。

replacements = Hash.new{|_, k| k}.merge(replacements.to_h)
dict.sort_by{|k,_| k.gsub(/./, replacements)}.to_h
