## From http://stackoverflow.com/questions/2311750/change-file-encoding-to-utf-8-via-vim-in-a-script

#This is the simplest way I know of to do this easily from the command line:

vim +"argdo se bomb | se fileencoding=utf-8 | w" $(find . -type f -name *.rb)

#Or better yet if the number of files is expected to be pretty large:

find . -type f -name *.rb | xargs vim +"argdo se bomb | se fileencoding=utf-8 | w"
