Re: [Exist-open] File upload leads to database crash

[Benoit M. <ben...@us...>]

I had the exact same problem few weeks ago with the char 😊 (U+1F60A 
<https://www.compart.com/fr/unicode/U+1F60A>) in a TEI document. I 
retested 10 minutes ago. Just creating a file with the following content 
from OxygenXML, performing an XQuery on//badChar and deleting the file 
(from Oxygen again) make my eXist server crashed. But few weeks ago the 
problem appeared while running Xqueries and/or reindexing, cannot 
remember, sorry.

    <debug>
         <badChar>😊</badChar>
    </debug>


[eXist Version : 6.2.0]
[eXist Build : 2023-02-04T22:42:29Z]

Hope this will help,

Benoit
