I (film) was dubbed a knight.
== Forms and variants ==In some sans serif typefaces, the uppercase letter I, 'I' may be difficult to distinguish from the lowercase letter L, 'l', the vertical bar character '|', or the digit one '1'
  In the Turkish alphabet, dotted and dotless I are considered separate letters, representing a front and back vowel, respectively, and both have uppercase ('I', '') and lowercase ('', 'i') forms
