This requires you to create three input files. 1. List of legacy fonts, eg. FM series which all use same mapping for Sinhala 2. Training text in legacy font, usually it will show up as garbled English 3. The above legacy text converted to Unicode, using an existing legacy to Unicode converter, these are available online
Using these 3 files, this script will generate tif image files, wordstr box files, lstmf files, it will also create a unicharset and all-lstmf file. You can use it in conjunction with tesstrain repo . I plan to add a pull request to the repo with the script along with some documentation.
