I18N In Production Server

My production server size is very limit (only 25MB)

YII framework folder size is around 22MB.

My question is,

The folder "i18n" size is around 11MB.

If I remove that folder from production environment, does it affect anything…?

my website doesn’t use any Internationalization options.

YII framework version is 1.1.10

I18N lib not is used just on internationalization features, but too on head language tags, characteres encodes, and default languages options.
