I am writing Julia code in Emacs, which allows the use of unicode characters in the source code. However, some symbols come out looking weird. For example the Greek letter nu:

becomes:

Does anyone know how to fix this to be the correct lowercase nu letter?

    What does Emacs say the character information is if you run C-u C-x = (which is the what-cursor-position command) with the point on that character?

  • Char: C-j (10, #o12, #xa) point=4118 of 4204 (98%) column=7

    C-j (10) is a newline. You surely want the previous character.

    @Drew I believe that Julia Mode looks for the escaped name of certain common symbols and then replaces them with their proper unicode character (e.g. \nu gets replaced with ν). There's a file (julia-mode-latexsubs.el) in the Julia Mode source that makes a hashtable of these mappings; the most recent version seems to have the correct mapping for \nu. I wanted to see what the character was that got inserted (in the second screenshot) to see if the correct character is being substituted or if it is just a font issue (or something of a similar nature).
