ESPERANTO ORTHOGRAPHY
Esperanto is written in an alphabet of 28 letters. However, only 22 of these letters can be found in the standard ASCII character set. The remaining six --- `c', `g', `h', `j', and `s' with circumflex, and `u' with breve --- are not available in ASCII; neither are they among the characters available in the common 8-bit ISO-8859-1 character encoding. Therefore, while the six special Esperanto characters pose no problem for handwritten texts, they were impossible to represent on standard typewriters, and are somewhat problematic even on modern-day computers. Various encoding systems have been developed to represent Esperanto text in printed and typed text.POSTFIX-h NOTATION
This was the solution proposed by the creator of Esperanto, L. L. Zamenhof. He recommended using `u' for `u-breve' and appending an `h' to a letter to indicate that it should have a circumflex. However, the letters `u' and `h' are already part of the Esperanto alphabet, so using them for another purpose invites ambiguity and mispronunciation. It also makes conversion of Esperanto text to postfix-h notation `lossy' or one-way; it is generally not possible to convert from postfix-h notation via automated means. This notation suffers from the additional drawback that the text cannot be sorted with standard rules for ASCII text.POSTFIX-H NOTATION
This is the same as postfix-h notation, except that `H' is used instead of `h' following a capital letter.POSTFIX-x NOTATION
This is the most common ASCII notation encountered today. It involves appending an `x' to a letter to indicate that it should have an accent (be it circumflex or breve). Since `x' is not a letter in the Esperanto alphabet, no ambiguity results. However, ASCII sorting algorithms still fail with postfix-x text.POSTFIX-X NOTATION
This is the same as postfix-x notation, except that `X' is used instead of `x' following a capital letter.PREFIX- AND POSTFIX-CARET NOTATION
Two slightly less popular ASCII encodings are to prepend or append a caret (`^') to a letter to indicate that it should have an accent.ISO-8859-3 (LATIN-3)
ISO 8859-3, also known as Latin-3 or South European, is an 8-bit character encoding for Esperanto. High-bit characters are used to encode the accented Esperanto letters. ISO-8859-3 can also be used for encoding English, Finnish, German, Italian, Latin, Maltese, Turkish, and Portuguese, making it useful for texts which mix Esperanto with one or more of these languages.UNICODE (ISO/IEC 10646)
Unicode is a standard for matching every character of every human language to a specific code. The mapping methods are known as Unicode Transformation Formats (UTF). Among them are UTF-32, UTF-16, UTF-8 and UTF-7, where the numbers indicate the number of bits in one unit.LaTeX SEQUENCES
The popular LaTeX typesetting package is capable of representing virtually any accented character. Note that conversion from LaTeX sequences assumes that characters to be accented are enclosed in braces --- for example, `\^{C}' will be recognized as `C' with circumflex, but `\^C' will not be.HTML ENTITIES
Unicode codes for Esperanto characters can be escaped in HTML documents by using HTML entities. The codes can be represented in either decimal (base-10) or hexadecimal (base-16) notation; the two are functionally equivalent.BUGS AND LIMITATIONS
Because the postfix-h and postfix-H notations are inherently ambiguous, conversion from postfix-h or -H text is unlikely to result in coherent text. Use at your own risk, and carefully proofread the results.Report bugs to <[email protected]>.
