将Unicode字符串转换为ASCII [英] Converting Unicode string to ASCII

问题描述

我有一些字符串，这些字符串包含ASCII找不到的字符；例如á，é，í，ó，ú；我需要一个函数将它们转换为可接受的内容，例如a，e，i，o，u.这是因为我将根据这些字符串创建IIS网站(即，将它们用作域名).

I have strings containing characters which are not found in ASCII; such as á, é, í, ó, ú; and I need a function to convert them into something acceptable such as a, e, i, o, u. This is because I will be creating IIS web sites from those strings (i.e. I will be using them as domain names).

推荐答案

function Convert-DiacriticCharacters {
    param(
        [string]$inputString
    )
    [string]$formD = $inputString.Normalize(
            [System.text.NormalizationForm]::FormD
    )
    $stringBuilder = new-object System.Text.StringBuilder
    for ($i = 0; $i -lt $formD.Length; $i++){
        $unicodeCategory = [System.Globalization.CharUnicodeInfo]::GetUnicodeCategory($formD[$i])
        $nonSPacingMark = [System.Globalization.UnicodeCategory]::NonSpacingMark
        if($unicodeCategory -ne $nonSPacingMark){
            $stringBuilder.Append($formD[$i]) | out-null
        }
    }
    $stringBuilder.ToString().Normalize([System.text.NormalizationForm]::FormC)
}

结果函数将以下列方式转换变音符号:

The resulting function will convert diacritics in the follwoing way:

PS C:\> Convert-DiacriticCharacters "Ångström"
Angstrom
PS C:\> Convert-DiacriticCharacters "Ó señor"
O senor
