I cannot reproduce this.  If I start an Emacs session exactly like you
say, with the file you attached, I get correct display and
capitalization does work for me.

What does "C-h c M-c" say?

Also, what does Emacs show when you put the cursor on the caharcter
you just applied M-c to, and type "C-u C-x ="?

Neither.  It's some strange issue specific to your system, I think.
