==== Alphabet ====
The Esperanto alphabet is based on the [[Latin script]], using a one-sound-one-letter principle, with the exception of [d͡z]. It includes six [[Letter (alphabet)|letters]] with [[diacritics]]: five with circumflexes (⟨ĉ⟩, ⟨ĝ⟩, ⟨ĥ⟩, ⟨ĵ⟩, and ⟨ŝ⟩), and one with a [[breve]] (⟨ŭ⟩). The alphabet does not include the letters ⟨q⟩, ⟨w⟩, ⟨x⟩, or ⟨y⟩, which are only used in the writing of proper names and unassimilated borrowings.

The alphabet was designed with a French typewriter in mind, and although modern computers support Unicode, entering the letters with diacritic marks can be more or less problematic with certain operating systems or hardware. One of the first reform proposals (for [[Esperanto 1894]]) sought to do away with these marks and the language [[Ido]] went back to the basic Latin alphabet.
