Converting "UTF8" files to other encodings in Text Wrangler

Question

Hi and thanks for your help
I have several text files I can easily use in different ways using Text Wrangler.
I need to convert text files originally written with different enchodings and I get errors.
I can overcome this using this script:
tell application "TextWrangler"
   tell document 1
       set line breaks to Unix
       set encoding to "Cyrillic (Windows)"
   end tell
end tell
However my attempts to create a loop always return this error
TextWrangler got an error: An unexpected error occurred while processing an Apple Event (MacOS Error code: -10000)
What is wrong with my script?
set inputfolder to (choose folder)
set theFiles to list folder inputfolder without invisibles
tell application "TextWrangler"
repeat with x from 1 to count of theFiles
          set thefile to item x of theFiles
          set inputfile to quoted form of (POSIX path of inputfolder & thefile)
  set line breaks to Unix
       set encoding to "Cyrillic (Windows)"
   end tell
end repeat

Answer 1

If its not typo you have the end tell inside the end repeat. Should be the other way.
      set encoding to "Cyrillic (Windows)"
   end tell
end repeat
end
That shouldn't even compile.
