[basex-talk] Inconsistency of regular expression support in BaseX and GUI

Hello!

Today I noticed that I can successfully use the following regular expression inside XQuery but the same regexp fails when using it in the GUI's searchboxes (the ones appearing when pressing Ctrl+F) when enabling regular expression search.

This is the regular expression and probably it is the block escape that is causing the error:

(¹|²|³|\p{IsSuperscriptsandSubscripts})

The error message says:

"Regular Expression: java.util.regex.PatternSyntaxException: Unknown character property name {issuperscriptsandsubscripts} near index 37"

Probably the lowercaseing of the block escape name is causing the error and hopefully it can be fixed without too complex logics.

Best regards
