As I noted above, I quite agree that these logical symbols should be added
to the list of special characters in LibreOffice Math. However, until they
are, there exists a workaround for Windows users, which even works with
Windows 7 (checked on 64-bit Win7 Pro) ; namely, to install UnicodeInput (
http://www.fileformat.info/tool/unicodeinput/index.htm). Note, however, that
(for me at least), it is not the hex code, but rather the decimal code that
must be used to import the glyph ; thus entering «2204» (without the
quotation marks) in the tool gives me the desired ∄, whereas entering
«089c»gives me a glyph I cannot read ࢜ with the fonts I have installed on
Win7....
