clearText(x, ascii = TRUE, encoding = "", lowercase = TRUE,
  trim = c("both", "left", "right", "none"), single_space = TRUE,
  alphanum = FALSE, other_char = " ")

`x`	a character vector
`ascii`	if `TRUE` then string is converted to ASCII using `iconv`
`encoding`	encoding parameter passed to `iconv`, if `encoding = ""` is used, then `iconv` uses the default system encoding
`lowercase`	if `TRUE` characters are transformed to lowercase
`trim`	parameter passed to `trimws`, if `trim = "none"` then white spaces are not trimmed
`single_space`	if `TRUE` duplicated spaces are removed
`alphanum`	if `TRUE` non alphanumeric characters are replaced with value provided in `other_char`
`other_char`	replacement value for non alphanumeric characters, space by default
