commit 51ec16b6c77222aa018959e165adc29d3b9648e5
Author: Enrico Forestieri <for...@lyx.org>
Date: Sun Feb 28 00:33:43 2021 +0100
Fix bug #3751
We lack the necessary font (cmb10) for drawing bold uppercase greek
letters. It would be overkill adding it for this sole purpose, so
adopt the same poor man's bold strategy used with \boldsymbol.
