This is an easy and safe change Actually, "allowing parallel configuration of TeX and non-TeX fonts" is a precondition for the proposed config value "automatic" for "use non-TeX fonts": * Currently, the LyX file stores font configuration only for one font set, either TeX-fonts or non-TeX-fonts, however * documents with non-default fonts usually require configuration for both sets to get a consistent look (e.g. choose Times/Helvetica/Courier lookalikes or "Linux Libertine" fonts - be it 8-bit or Unicode encoded fonts). * Documents using non-Latin scripts or "exotic" accented characters may even fail to compile with the default fonts (either TeX or non-TeX) due to our new "missing character" error.

As said above, many documents that shall work with XeTeX "in principle" require font customization with non-TeX fonts. Maybe we need a "default non-TeX fonts mechanism" for non-Latin scripts. Günter
