Editing Box files

[anne]

Haloo, I want to train Tesseract on a new script but I'm confused when it comes to editing the box file. The script looks like this

and after generating the box file (with eng as basis) I got this

Now my problem is that I'm confused on how to edit/change the values. Do I need to replace the english letters with my language's symbols? Or do I just need to edit the numbers? Thank you in advance.

It means that the font you are using has mapped English letters to these symbols. If you view the box file in that same font the symbols should show. Possibly the numbers for coordinates will also show up as symbols, based on the mapping.

I assumed that you used text2image to generate the box/tiff pairs using a font for your `language`.

I used this line

tesseract [lang].[fontname].exp[num].tif [lang].[fontname].exp[num] batch.nochop makebox

from https://github.com/tesseract-ocr/tesseract/wiki/Training-Tesseract-%E2%80%93-Make-Box-Files

Tesseract generates unicode output after recognizing.

Are there any unicode points for symbols that you have used?

How do you type out those symbols?

I found the unicode for Baybayin (which is the language) which is this

As for typing out those symbols, there are only a few keyboards that support it because there is not enough research on the language as of now.

[Shree Devi Kumar]

I found couple of unicode fonts that can display the tagalog range -

 "Quivira" \

 "Noto Sans Tagalog" \

Using these it will be possible to train for  for Baybayin .

Does the language use any punctuation and numbers?

for box/tiff pairs

[Christine Anne Catubig]

No, I'm not including punctuations and numbers. Thank you so much though for the box/tiff pairs. You're a life saver. Thank you.
