Convert UTF-16 to UTF-8 under Windows and Linux, in C

Question

I was wondering if there is a recommended \'cross\' Windows and Linux method for the purpose of converting strings from UTF-16LE to UTF-8? or one should use different method

Answer 1

Change encoding to UTF-8 with PowerShell:

powershell -Command "Get-Content PATH\temp.txt -Encoding Unicode | Set-Content -Encoding UTF8 PATH2\temp.txt"
