Missing Dependency on lm-math package #491

Closed e-kwsm closed 5 years ago

e-kwsm commented 5 years ago

Description

tlmgr shows dependency of unicode-math, i.e. only on fontspec:

$ tlmgr info --data localrev,depends unicode-math
48309,fontspec

But unicode-math uses Latin Modern Math, provided by lm-math, unless math font is loaded.

Hmm, good point if unicode-math is installed using a "minimal" TeX Live system. I can improve the readme, and then when the update is sent to CTAN I can flag with the tlmgr people (maybe that just means the TeX Live people).
