LyX for Windows offers incomplete support for non-TeX fonts. This is the case, for example, of the Gyre Schola font, which although proposed by Miktex 2.9 , is unknown to LyX 2.3 RC2 (this is not the case of LyX 2.3 compiled under Linux Ubuntu 16.04).

The filename of the > backup file will be: > ORIGNAME-lyxformat-NUM.lyx~ > where NUM is the LyX format number of the original file.
