[问题求助] 用PowerShell保存为UTF-8无BOM[已解决]

smss

$str = [IO.File]::ReadAllText('manifest.xml', [Text.Encoding]::UTF8);
$str = $str -replace '(?m)^\s+|\s*(?:\n|$)' -replace '<!--(?:(?!-->).)*-->';
[IO.File]::WriteAllText('1.xml', $str, [Text.Encoding]::UTF8);COPY

smss

回复 6# xczxczxcz

$MyFile = Get-Content '1.xml'
$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
[System.IO.File]::WriteAllLines('1.xml', $MyFile, $Utf8NoBomEncoding)COPY

自测可以啊 先用Notepad++弄个有BOM 的1.xml 再运行可以正常啊

昨晚试了下，PS的cmdlet及参数中还真没找到能把utf8-rom转utf8的。有可能姿势不对，但使用NET库就一句话搞定。

很直白的伪代码：
$UTF8 = $UTF8withBOM;
$UTF8 =~s/^\xef\xbb\xbf//;
write_file( "UTF8noBOM.txt",  {binmode=>":raw"}, $UTF8 );

试试转为字节，再16进制，除前面3个字节，再转为字符串。我还没测试过。

smss

$str = [IO.File]::ReadAllText('manifest.xml', [Text.Encoding]::UTF8);
$str = $str -replace '(?m)^\s+|\s*(?:\n|$)' -replace '<!--(?:(?!-->).)*-->';
[IO.File]::WriteAllText('1.xml', $str, [Text.Encoding]::UTF8);
$MyFile = Get-Content '1.xml'
$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
[System.IO.File]::WriteAllLines('1.xml', $MyFile, $Utf8NoBomEncoding)COPY

感觉能再改改
