Take a text file of Coptic keyed in the unicode Coptic characterset. (SCRIPTORIUM uses the Antinoou font and keyboard.)
Save the file as a plain text file (.txt) encoded in UTF-8. (Most text editors have an option in Preferences for opening and saving texts in UTF-8.)
Be sure there is a space between each Coptic bound group. (You do not need to segment all the morphemes. We follow Layton's conventions for segmenting bound groups. For example ⲁϥⲟⲩⲱϣⲃ ⲛⲁϥ, not ⲁ ϥ ⲟⲩⲱϣⲃ ⲛⲁ ϥ, nor ⲁϥⲟⲩⲱϣⲃⲛⲁϥ. (Our Transcription Guidelines have more details.)
Mac users: save your text file using Unix line breaks/carriage returns. Most text editors have an option for toggling between Windows/Mac/Unix line breaks; we recommend the free texteditor Text Wrangler. This formatting option is displayed at the bottom of the window.
If you have a text in ASCII, in one of the old, pre-Unicode legacy fonts, such as Lasercoptic, it may be possible to convert your text using one of our character converters.
