Hi, The string is currently "There Not Exists" which doesn't seem correct according to Unicode: https://unicode-table.com/en/2204/ location of the string: https://git.libreoffice.org/core/+/master/starmath/inc/strings.hrc#143
Dante took care of it with https://gerrit.libreoffice.org/c/core/+/121482 for bug 144189
