我正在尝试使函数返回不带重音的给定字符串，但是iconv的//TRANSLIT选项似乎只将重音和字母分开而没有除去重音。
这是我的功能:
<?php
function strRemoveAccents($str)
{
return iconv(mb_detect_encoding($str), 'us-ascii//TRANSLIT', $str);
}
这是我的结果:
一些精度:
mb_detect_encoding对我的所有测试都返回“UTF-8”，并且用返回值替换该函数不会更改任何内容。 LC_COLLATE=C;LC_CTYPE=French_France.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C en_US.UTF-8(我检查了:语言环境已成功更新)，但是函数的返回仍然是c/fr_FR.UTF-8/c/c/c/c，问题仍然相同。 我可能会丢失一些东西，但是我看不到。
编辑:正如@jasonwubz在回答中所提到的，仅当使用 libinconv 时才出现此问题，而当使用 glibc 时则不存在。使用这些实现中的任何一种时，是否有办法使其工作？
最佳答案
变音符号的问题在于它们根据语言的处理方式不同，例如在阿拉伯语中，变音符号被认为是具有自己的Unicode代码点的字符，当它们加入阿拉伯字母时，它们仍然与父字母不同。 ，例如，这是Meem字母"م"，这是Dammah Diacritic "ُ"，当Dammah加入Meem时，字符串中的将是2个字符。 That is why you can post nearly empty posts on SE network with these types of diacritics
因此，从字符串中删除这些变音符号就像搜索这些〜8变音符号并将其替换为空字符串一样简单，同时保持父字母不变。
$withoutDiacritic = str_replace(['ٌ','ُ','ً','َ','ٍ'], "", $string);
拉丁字符的问题有所不同，当变音符号连接一个字母时，它们会产生一个带有自己的Unicode代码点的字母字符。例如，当您将变音符号加入字母
"e"时，它将被转换为另一个Unicode字符"è"，因此您无法通过搜索变音符号并将其删除来应用我们在阿拉伯变音符号中的操作，而是必须搜索"è"字符并替换它与"e"一起使用，这就是node diacritics的作用。我制作了PHP版本的node diacritics，不要忘了给这些家伙加注，因为他们做了所有繁重的工作。
