I found out that --fonts_dir="" reset fonts_dir variable to system default e.g. if --fonts_dir argument is not use text2image is looking for fonts in /auto/ocr-data/tesstraining/fonts

With --fonts_dir= text2image will search fonts from many directories. These directories are defined in a config file which is part of fontconfig. This is the situation on Linux at least.

/auto/ocr-data/tesstraining/fonts is probably Google-specific path. Clearly it is not a good default for non-Google users.

Here is one possible fix from my fork of text2image:
amitdo/text2tif-2016@ac0a24c93271

I'm not sure this is the 'right' solution.

Another way is to define a different default path for each OS (Linux, Mac, Windows).
