A new build of the console application exf has been posted.
Due to the way Windows handles Unicode output in consoles, exf was “terminating” batch files any time exf was called from a batch file. The only way I could find to fix this problem was to have exf revert the output mode to ANSI after the work is complete. What this means is that visually, Unicode characters in the console window will appear as boxes, but the actual data is still being written as Unicode. So, if you are redirecting output to a file, nothing is lost as the output is still UTF-8. It’s only what appears in the console window that is altered.
Anyway, this means you can now use exf properly in a batch file. Yay!
