In addition to Pierre-Yves's objection based on actual usage, here is some
background information:

According to Wikipedia [1] and Unicode's FAQ [2], before Unicode version 3.2
(released in 2002), U+FEFF had been called ZERO WIDTH NO-BREAK SPACE and used
both at beginning of a data stream to indicate byte order, or in the middle of
a data stream to adjust line-breaking.

Unicode 3.2 deprecated the latter usage of U+FEFF and renamed it to BYTE ORDER
MARK.  It also created U+2060 WORD JOINER for the latter usage and encourage
people to use it instead of U+FEFF in the middle of a data stream.

So it seems LibreOffice is just using an deprecated nomenclature in both code
and UI.  The most likely scenario is that the character inserted into documents
probably was changed from U+FEFF to U+2060 some time after 2002, but the
variable names and UI string were not.
