Good morning,

I have about 240 microsoft office word 2010 documents, all 9+ years old,
that I'm converting to LibreOffice Writer in Fedora-35.  I'm having to
do this in 3 steps:

1. In windows-7, content is copied from the word files to Writer files. 
Tweaks are made to line spacing in tables.  The word documents use two
fonts: Times New Roman (various sizes; sometimes regular, sometimes
italic, sometimes bold), and Vivaldi.  Writer in windows-7 seems to
support all the fonts used in the word documents.

I've been involved with conference proceedings where authors provided
documents with "Times" like fonts from different versions of Windows and
Office, including Japanese fonts (being used for English docuemnts).   The 
organizers attempted to share the originals, but many authors encountered 
problems with differences in fonts such as missing "ffi" ligatures, differences 
in fonts used for mathematics, italics generated by simply transforming an 
upright font, and "fake" caps and small caps fonts.   Open Office (this was 
before LO appeared) came to the rescue back then.
 

2. Writer files are copied to my Fedora workstation.

Unfortunately, neither Times New Roman nor Vivaldi are available in
Fedora-35.  So I need a step 3: to convert the fonts to choices that are
available in Fedora-35, and are expected to be available for a long time
to come.  It's that last condition that I need help with.  It's happened
to me in the past that a font that I used in Writer (in Fedora) ceased
to be available, so I changed it to the closest match that was
available.  Then that font ceased to be available.  So before I start
step 3 with them 240ish Writer files, how do I know which fonts are
likely to be permanent or supported in Fedora for many years, and which
are most vulnerable to being sunset sooner rather than later?

You should look for high quality open source fonts.  There is an abundance 
of low-quality open source fonts, many of which are not maintained and 
may not be available in the future.  

The <Scientific and Technical Information Exchange (STIX)>
project is supported by a consortium of publishers with the goal of making 
high-quality fonts that can be used across different software and can be expected
to be available for many years.


By the way, why do so many fonts show up twice in the font selection tools?

Different programs may install different versions.   You may have Type1, Truetype,
and or Opentype format files for the same font name, as well as multiple versions
in the same format.  Some systems provide aliased names so you can have
two different fonts showing under the same generic name.
