I have emacs-24.5 installed on Windows 10. Many utilities are configured through cygwin, including perl. When in Markdown mode every so often after I press C-c C-c p to run the external markdown.pl against the buffer contents and open the resulting markdown-output buffer in the browser, I instead see the following: The reason is that the original README.md file contains RIGHT SINGLE QUOTATION MARK character in UTF-8 format, which is the bytes E2 80 99, or 0x2019 code point in Unicode. markdown.pl interprets the character correctly in its output, I tried to run it from the command prompt and the resulting HTML is also in UTF-8 encoding.
Hence the question: how can I to configure markdown-preview function so as it sets markdown-output buffer coding system to utf-8 anytime I asked for markdown-preview?
