--- Comment #2 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Unicode in that range is all Private Use Area (PUA)

Two usage factors:

1. for working with PUA defined glyphs, you must make a font assignment on the
document canvas. Allowing default paragraph font, or a fall back font will
likely display junk.

2. If the font is not installed to system LO will search for a
fallback--checking every font on system for coverage of that PUA block--and
still may have the wrong glyphs rendered. Avoid that by always making a font
assignment--installing the font if necessary.

The PDF generator for some software will take valid fonts and cast them into
PUA areas to obscure the text strings--looks fine in the PDF but no means to
work with the PDF except with the source software.

Seems that is your situation, your PDF source program is working with PUA --
youu'll have to obtain the font/PUA mappings and either create a new font (e.g.
with Fontforge) or extract the font from the PDF, numerous utilities to do
that. But be mindful of licensing of the resulting font.
