Non ASCII words (commom in portuguese) trigers warnings
    in R CMD CHECK. To prevent this, enc{}{} must be
    used. This function gets a character and returns enc{}{}
    for all non ASCII words.
use_enc(x) enc_nize(file) enc_titles()
| x | character[1] A title to be converted. | 
|---|---|
| file | character[1] A R file with documentation written in
roxygen syntax.  | 
character[1] The converted character provided.
enc_titles applies enc_nize to all files in
    the ./R/ directory of a package. So, it is assumed that
    working directory is a root package directory. enc_titles
    modifies files. So be careful with its use.
