I agree.

In case someone wants to extract embedded fonts from a PDF file, there are
several programs and services for this purpose. Some are listed here:

How can I extract embedded fonts from a PDF as valid font files?

This is unfixable. Fonts embedded in PDF are not generally usable for editing.

1) They are usually subset fonts, so any character not used in the document
with any given font will be missing.
2) They are often Type 1 or bare CFF fonts and both we can’t use as standalone
fonts.
3) They also are usually stripped from any OpenType layout tables (so no
ligatures, kerning, Arabic or Indic support etc.)
4) Glyph are re-encoeded and the cmap table is not usually usable, since the
original Unicode encoding is lost.

The only case where the embedded fonts are usable is when full OpenType font is
embedded, and this rarely happens because of the file size implications.

My suggestion is to close as WONTFIX.

On Windows build of 6.3.2.2

attachment 154867 from dupe issue opens with fallback (poorly), but inserts as
image cleanly.

No, please look more closely...  

The ipdf filter to insert is now pdfium based and handles subset fonts
correctly, rendering a high fidelity but low resolution bitmap to document
canvas. 

But the pdfimport filter continues to use fall back font substitution rather
than parsing the subset fonts. Poor fidelity to original fonts, but as high
resolution vector font draw objects.  Issues when the fall back replacment
lacks coverage of a code point--or the source font uses private use addressing
(PUA).

Created attachment 128030
  --> https://bugs.documentfoundation.org/attachment.cgi?id=128030=edit
PDF sample

I'd just tested today's 5.3 alpha build and found this problem when inserting a
PDF as an image into Writer. All text (numbers and Greek characters) are in the
wrong font.

Attached is a simple PDF created when testing LabPlot software. The PDF looks
Ok on Okular and on its properties it shows the font is correctly embedded. 

Note that the font is substituted even if it is present on the system. 

If the PDF is turn into SVG and then inserted, the SVG works without a problem.
