While plaing dunnet, saving games via the "save"-command fails with the message "Error saving to file". To reproduce: $ ~/src/emacs/src/emacs -batch -l dunnet Dead end You are at a dead end of a dirt road. The road goes to the east. In the distance you can see that it will eventually fork off. The trees here are very tall royal palms, and they are spaced equidistant from each other. There is a shovel here. >save /tmp/foo.txt Error saving to file. > The reason is that dunnet uses its own implementation of ROT13 to obfuscate the savefile, and this implementation breaks when it encounters characters outside the 0-255 range. On 2015-08-24, Paul Eggert introduced some curly quotes in data normally saved to this file. Attached is a patch that makes dun-rot13 use rot13-region instead of its own implementation.
