> In the end the file is generated and properly saved, but some letters are
> missing (like "ft" in "software" or "ff" in "different"). So far I've tested
> close to 10 files and this is the only problematic item I've found. Depending
> on what program I use to view the resulting .txt file, I either get blank
> spaces (Notepad) or "NUL" values (Notepad++) in place of the missing letters.
> What's more, some editors (Sublime Text Editor) outright refuse to open the
> file and view it as unreadable/corrupted byte code. Suffice to say working
> with such a file is somewhat difficult...
