Note that in many software environments the Greek alphabet, and often a subset of the escape codes, will be translated into their proper forms. Accents and diacritical marks are written directly after the coding for the character above and below which they are located in the source document. Introduction Information about the printed text which cannot be conveyed by the alphabetic encoding system is represented by various escape codes.
All escape codes are in the form of a single symbol followed by a numeric modifier.
Nonetheless, editors use sigla in idiosyncratic fashion, and the categories offered here should be used with appropriate caution. The TLG author-number in parentheses which sometimes follows an escape is given as the locus for an intricate or otherwise difficult symbol. Certain escape codes in the tables are marked obsolete. This means that, while the code may or may not be found in existing texts in the data bank, it is no longer employed in texts currently being added. In order to avoid duplication of escape sequences, the TLG coordinates its use of escape codes with other data entry projects.
