Use iconv from GNUWin32 pack. It is much faster, especially if your files are about or more than 1 Gb.

"C:\Program Files (x86)\GnuWin32\bin\iconv.exe" -f cp1251 -t utf-8 source.txt > result.txt

Here is for each convert *.text file to *.sql file:

foreach ($file in get-ChildItem *.txt) {
    Echo $file.name
    Get-Content $file | Set-Content -Encoding utf8 ("$file.name" +".sql")
 }
