Antheia (latest version 3.0.0) is a plain text editor that enables users to type hundreds of different characters by entering (usually fairly easy to remember) sequences of 1, 2 or 3 ASCII-characters. The character that will be inserted into the current document, will also depend upon the script mode that the application is in. For instance, if you press the key that would normally be used to type the letter y, Antheia will display the same letter y in Latin mode, but the Greek letter υ in Greek mode, the Cyrillic letter ы in Cyrillic mode and the Thai letter in Thai mode. An example of a sequence that consists of more than one character is 'a (single quote plus small letter a), which results in Antheia converting this sequence to á in Latin mode and to ά in Greek mode.

Antheia currently supports the following script modes:

Arabic ASCII * Baybayin Buhid Canadian
Cherokee Coptic Cyrillic Deseret Gothic
Greek Hanunó’o Hebrew IPA Lao
Latin N’Ko Ogham Old Persian Runic
Shavian Tagbanwa Thai Tifinagh Vai

* In script mode ASCII no character translation occurs, so when you type for instance 'a in this mode, a single quote followed by a small letter a will be inserted into the current document. Despite its name it is possible to type non-ASCII characters in this mode if your operating system and/or keyboard allows it.


* Antheia can only display characters that are supported by the selected font. If a font does not support the character that you typed, a generic placeholder indicating the missing character will be shown instead (often a small rectangle). In fact the character is not missing from the document, it just cannot be displayed and it might be shown properly when you select another font that does support it (either in Antheia or another application).

Fonts that can be used with Antheia must be Unicode TrueType fonts. Some of these fonts support thousands of characters, while others only support a small subset. If none of the fonts that are distributed with Windows, support the entire range of characters that you need to use in your document, you will have to find and install one that does. You can here find a table of the most commonly used Unicode fonts that support a large number of characters.

Antheia can only use TrueType fonts, however, selecting some TrueType fonts (e.g. Code 2000) in the font dialogue box results in the apparently incorrect error message “Only TrueType fonts are supported and this is not a TrueType font”. This seems to be a bug in a Windows component, and currently we do not know if we can circumvent it somehow.
