LaTeX token don't work correctly about libtexprintf HOT 2 CLOSED

And

❯ utftex '\frac  {1}{\alpha^2}'

ERROR: Too few mandatory arguments to command (1x)

spaces between command and arguments don't work, while being valid LaTeX syntax.

from libtexprintf.

Hi, you found two bugs, I did not skip spaces between the command and its arguments, and I did not properly handle multi-byte UTF-8 arguments without brackets (a pre-processor replaces the '\alpha' with α before I parse the arguments). I pushed a fix to dev branch.
Thanks
