Am I interpreting your message (and specifically the word "new" in the subject) correctly as meaning that the latest lxml release, 4.7, behaves differently from the previous one, 4.6.5, for you with respect to the specific XML Schema construct that you provided? lxml 4.7 uses the latest version 2.9.12 of libxml2 (which implements the XML Schema support, lxml does not do that itself). 4.6 still uses the older 2.9.10 (and actually 2.9.4 on Windows). You may be able to stick with that. Sadly, libxml2 is currently not maintained, so a fix (assuming that this really is a bug) is unlikely to happen on their side any time soon. Stefan
This pattern validates in xmllint from libxml2 <xs:pattern value="[€ȘșȚț\p{IsBasicLatin}\p{IsLatin-1Supplement}\p{IsLatinExtended-A}-[\p{C}]]+"/> It seems to do the same evaluation, although does not 'fix' the bug.

Was there an announcement to that effect since the most recent release (which was in May of this year)? https://mail.gnome.org/archives/xml/2021-July/msg00000.html
