Nothing new here.
This is mostly caused by mismatch between the font names recorded to the PDF
and the font names as installed to your system. The names don't match and the
os attempts fall back replacment. When imported to Draw, we don't make much
use of the minimal font set recorded into the PDF, and the rest of the draw
objects get fallback which may or maynot result in good quality rendering of
the text runs--even more of an issue with CJK fonts.
However, the project also provides the Chromium projects "pdfium" based insert
filter. Because it uses the exact fonts for strings contained in the PDF it can
render with very good fidelity to the original PDF. The default resolution is
set low for performance, but can be increased by setting a
PDFIMPORT_RESOLUTION_DPI environment variable. Insertion of the PDF as an image
at 600 dpi or 1200 dpi will satisfy most work flows for high quality rendering
of PDF to an ODF document canvas.
So, give the pdfium "Insert" filter a test. Issues with the PDF "Import" filter
are unlikely to be fixed, especially the odd results for multi-byte glyph text
streams.
