Notes on importing Hebrew text from BibleWorks. This works fine, but when converting the text to Unicode during import, the encoding "Windows-1252" gives best results. The screen fonts needs to be set to "Bwhebb". This font should be copied from the BibleWorks installation and installed in Linux. If the llines of this visually ordered Hebrew text are too long, then use "Tools - Line cutter for Hebrew text" to shorten the lines.
Mechon Mamre has a good quality Hebrew text, with vowels and cantillation marks.
To import this Hebrew text into Bibledit, do this: Go to http://www.mechon-mamre.org, and download the Hebrew Bible with cantillation marks, see the offline resources section, the individual HTML Bibles in ZIP files. This gives a file ct005.zip. Unzip this file. The individual files can then be found in subdirectory c/ct in the directory where you unzipped the file. Point the Import text dialog to this directory, and set the import type to Mechon Mamre. Then finish the import. The screen font can be set to "Ezra SIL" or similar.
