I realized today there can be an issue in Geany core, as text files which inadvertently contain character '\0' (NUL character) in the middle of it (for instance, a log file), are only read (or represented) until that point. I have tested both Geany 1.38.0 and Geany 2.0, and both of them behave in the very same way.
Comparatively, I have tried other editors, like vim, nano, Kate or the ancient NEdit, and no one of them suffer from this bug.
Could you fix it, please?
