GoSaveTool.Text (GoSaveTool v1.0.0)

Word, character and reading-time counts, social media character limits, case changes, URL slugs and whitespace cleanup. The Elixir version of @gosavetool/text.

Online counter: https://www.gosavetool.com/character-counter

iex> GoSaveTool.Text.title("the lord of the rings: return of the king")
"The Lord of the Rings: Return of the King"

iex> GoSaveTool.Text.slug("Ölçü Birimi & Çeviri!")
"olcu-birimi-ceviri"

Characters are Unicode code points, so an emoji counts as one (not graphemes, as String.length/1 counts).
