--text follows this line-- I wrote a custom function that let me preview a Markdown buffer in Marked, which utilizes shell-quote-argument to export the path to the file being edited in Emacs to Marked.app. It works well until it encounters file names or paths with Chinese characters. The Chinese characters are wrongfully escaped. For example: (shell-quote-argument "/Users/user/中文目录/中文file.txt") evals to "/Users/user/\\中\\文\\目\\录/\\中\\文file.txt" The shell-quote-argument function yields the same output under a new emacs instance started with `emacs -q`, so this should not be related to my configuration. A quick look of the function in question shows that it just escapes all non-ASCII characters, and the escaped Chinese characters cannot be correctly recognized by either bash or zsh. Shouldn't the regexp in the function be more discriminative and recognize, say, unicode characters allowed in file names and paths? I think very few people use (or know) any shell that recognize a unicode smiley (U+263A) as a command, but many use a language they speak to name files.
