How to use the enca package, in particular the enconv utility to convert files?

Question

PHP

I need to recode the folder with the installation files from UTF-8 to CP1251, How to do something like found it - use the utility - enconv from the enca package:
using the command: find . -type f -name '*.php' -exec enconv -V --convert-to=CP1251 '{}' ';'
But I don’t know how to use the utility itself - enconv from the enca package. Googled for 2 days and still can't figure it out.
I downloaded the enca 1.18 package for windows,

Use standard utilities to convert icons and all that.
