问题描述

我需要能够对用户的输入转换为[AZ]罗马字符只（不区分大小写）。所以，只有26个，我感兴趣的是人物。

I need to be able to convert user input to [a-z] roman characters ONLY (not case sensitive). So, there are only 26 characters that I am interested in.

但是，该用户可以键入在那些他们希望的任何字符形式。西班牙N，法国的E，和德国U都可以有用户输入口音（这是由程序中删除）。

However, the user can type in any "form" of those characters that they wish. The Spanish "n", the French "e", and the German "u" can all have accents from the user input (which are removed by the program).

我已经得到了pretty的接近与这两个扩展方法：

I've gotten pretty close with these two extension methods:

    public static string LettersOnly(this string Instring)
    {
        char[] aChar = Instring.ToCharArray();
        int intCount = 0;
        string strTemp = "";

        for (intCount = 0; intCount <= Instring.Length - 1; intCount++)
        {
            if (char.IsLetter(aChar[intCount]) )
            {
                strTemp += aChar[intCount];
            }
        }

        return strTemp;
    }

    public static string RemoveAccentMarks(this string s)
    {
        string normalizedString = s.Normalize(NormalizationForm.FormD);
        StringBuilder sb = new StringBuilder();

        char c;
        for (int i = 0; i <= normalizedString.Length - 1; i++)
        {
            c = normalizedString[i];
            if (System.Globalization.CharUnicodeInfo.GetUnicodeCategory(c) != System.Globalization.UnicodeCategory.NonSpacingMark)
            {
                sb.Append(c);
            }
        }

        return sb.ToString();
    }

下面是一个例子测试：

string input = "Àlièñ451";
input = input.LettersOnly().RemoveAccentMarks().ToLower();
console.WriteLine(input);

结果：外星人（预期）

这适用于99.9％的情况下。然而，一些人物似乎通过所有的检查。

This works for 99.9% of the cases. However, a few characters seem to pass all of the checks.

例如，SS（德国双S，我认为）。这被认为是由净是一个字母。这不是由上面的函数被认为有任何重音符号...但它仍然不是在z的范围内，就像我需要它。理想情况下，我可以将此转换为B或SS（以适用者为准），但我需要将其转换为一些在亚利桑那州的范围内。

For instance, "ß" (a German double-s, I think). This is considered by .Net to be a letter. This is not considered by the function above to have any accent marks... but it STILL isn't in the range of a-z, like I need it to be. Ideally, I could convert this to a "B" or an "ss" (whichever is appropriate), but I need to convert it to SOMETHING in the range of a-z.

又如，所述dipthong（AE）。此外，净认为这是一个信。功能上面没有看到任何的口音，但同样，它不是在罗马26个字母。在这种情况下，我需要转换为两个字母AE（我认为）。

Another example, the dipthong ("æ"). Again, .Net considers this a "letter". The function above doesn't see any accent, but again, it isn't in the roman 26 character alphabet. In this case, I need to convert to the two letters "ae" (I think).

有没有一种简单的方法来转换任何世界各地输入到最接近的罗马字母相同呢？据预计，这可能不会是一个完全干净的翻译，但我需要相信，输入在FlipScript.com只得到字符AZ ......而已。

Is there an easy way to convert ANY worldwide input to the closest roman alphabet equivalent? It is expected that this probably won't be a perfectly clean translation, but I need to trust that the inputs at FlipScript.com are ONLY getting the characters a-z... and nothing else.

任何和所有帮助AP preciated。

Any and all help appreciated.
