About Source Input

After this study, i realized that the size of input does not matter much. It is not necessary to gather thousands of source code files. 20 or 50 files from a generic project is sufficient.

For certain languages, different projects do favor certain chars, but again, not overall significant.

For example, for python, just pick 20 files from standard library is good enough. No need to go out of the way to get source from different projects.
