unicode - Change files' encoding recursively on Windows?

Question

Does anybody know a tool, preferably for the Explorer context menu, to recursively change the encoding of files in a project from ISO-8859-1 to UTF-8 and other encodings? Freeware or not too expensive would be great.

Edit: Thanks for the answers, +1 for all of then. But I would really like to be able to just right click a folder and say "convert all .php files to UTF-8". :) Further suggestions are appreciated, starting a bounty.

Answer 1

You could easily achieve something like this using Windows PowerShell. If you got the content for a file you could pipe this to the Out-File cmdlet specifying UTF8 as the encoding.

Try something like:

Get-ChildItem *.txt -Recurse | ForEach-Object {
$content = $_ | Get-Content

Set-Content -PassThru $_.Fullname $content -Encoding UTF8 -Force}
