Other case Л of л is not in unicharset

[roberty...@gmail.com]

Hello,

I use the new tutorial to fine tuning the traineddata. I want to add some specific symbols to the existing chi_sim.traineddata model.

First, I use the command: training/tesstrain.sh --fonts_dir /usr/share/fonts --lang chi_sim --linedata_only --noextract_font_properties --langdata_dir ../langdata --fontlist "SIMSUN" --tessdata_dir ./tessdata --output_dir ~/tesstutorial/trainspecial to create the new training data. But some specific symbols cannot be added to the unicharset file.

A part of output information showed following:

which shows that some specific symbols such as 'Л', '》', ...,   cannot be added to the unicharset.


How can I add these symbols to the unicharset? Should I add them manually?
