software, Word, Greek

Theuth is a Word addin you can use to ease the typing of Greek and Latin text with all their diacritis and symbols, and to convert text written with any arbitrarily-encoded Greek font into a standard Unicode font, or vice-versa. This is often a pain especially for editors in publishing Greek texts, as there are still several users who rely on the never too blamed habit of using custom, arbitrarily designed fonts for representing Greek instead of just leveraging the Unicode standard. You can read more about this issue in chapter I.2 of my book.


 Theuth adds a new ribbon to Word, which gives you access to all the essential functions of this addin:

  • the panel button shows the Theuth action panel to the right side.
  • the code button shows information about the code of the character preceding the caret.
  • the selection button shows information about the codes of the selected text.
  • the change font button is a quick way of replacing all the occurrences of an input font into an output font. This is not an encoding conversion, but just a font replacement. For conversions, see the conversion panel.
  • the change codes button systematically replaces a set of character codes with another one.
  • the find regex button can be used to find the text matching a specified regular expression.
  • in the diacritics group you can find all the buttons to add or remove diacritics from the character to the left of the caret. Each button acts as a switch, toggling the diacritic on and off. The software knows which combinations of diacritics are allowed, thus automatically combining them and discarding the incompatible ones. This is a more user-friendly way of typing Greek polytonic texts, as it allows you to type first letters and then diacritics, while a typical keyboard layout requires you to do the contrary. Such buttons work also for non-Greek characters, e.g. for adding accents to an Italian text or umlauts to a German one. The X button clears all the diacritics at once.
  • the hotkeys group allows you to select hotkeys for toggling diacritics without using the mouse. You must enable hotkeys for this to work, and you can define your own combinations by simply selecting the desired command and pressing the desired keys.


The symbols panel allows you to quickly insert your favorite symbols. You can add new symbols by simply entering their code and clicking the plus button, reorder them with the arrow buttons, colorize them with the dropdown colors (colors are automatically assigned according to the Unicode category), and save or load the set of symbols in a text file.


The Unicode panel allows you to browse the Unicode standard to quickly find the characters you are interested in. This panel uses the same component leveraged by UniSpy, so you can see this application for more.


The info panel shows information about the codes of a single character or the selected text: just click the info button on the ribbon to get these codes displayed in the info panel. You can also directly type a character code (either in hexadecimal or in decimal, in tha latter case checking the 10 option) and see information about it. This panel uses the same component leveraged by UniSpy, so you can see this application for more.


The conversion panel is used for converting your text encoding. Most of times you will use it to convert a Greek text written using a non-standard font (e.g. Graeca, SuperGreek, Greek and the like) into Unicode, or vice-versa, but you can also convert text from or to Beta code and transliterate Greek text. Just select the font used by the text you want to convert (source) and one or more target fonts from the list (if converting from font to font), then click the thunderbolt button. The topmost dropdown list allows you to choose the conversion operation (font to font, Beta code to font, font to Beta code, or Greek transliteration). Once you start the conversion, all the text formatted with the source font will be converted, while keeping the rest of your document unchanged. The conversion starts from your cursor position.
