Esperanto orthography
Esperanto is or done as the reaction to a question in a Latin-script alphabet of twenty-eight letters, with upper in addition to lower case. This is supplemented by punctuation marks & by various logograms, such as the digits 0–9, currency signs such(a) as $ € ¥ £ ₷, and mathematical symbols. The creator of Esperanto, L. L. Zamenhof, declared a principle of "one letter, one sound", though this general guideline is not strictly followed.
Twenty-two of the letters are identical in draw to letters of the English alphabet q, w, x, and y being omitted. The remaining six construct circumflex, and u breve.
