> Some symbols are sometimes not being treated correctly depending on what
> characters follow. For example, I have the following setup for coding
> Python:
> (prettify-symbols-mode t)
> (global-prettify-symbols-mode t)
> (add-hook 'python-mode-hook
> (lambda ()
> (push '("**2" . ?²) prettify-symbols-alist)
> (push '("_x" . ?ᵪ) prettify-symbols-alist)
> (push '("delta" . ?δ) prettify-symbols-alist)))
Can you try the patch below and see if it does what you want?
