Font (MT Symbol)

[mcdon47]

I am writing a large (UK A4 size) resource book which will be printed. The font needs to be large (16 to 18 pts) and the print clear and not too heavy. I particularly like ‘MT Symbol’ in LibreOffice Writer and it seems ideal for our need. However, in the list of Font from the menu bar, I see strange looking characters or symbols to the right of ‘MT Symbol’ and there are others in the list of some fonts. What are they?

Is ‘MT Symbol’ safe to use? Will it be around for a few years?
I intend to export to PDF when ready to print.
Thanks.

MT Symbol is completely unrelated to LibreOffice, and is one of proprietary fonts supplied along with MathType software. How it is maintained, licensed, distributed, and what are plans on its future - all these are questions to respective entities, and is not something to discuss on this site.

That font is likely to be a symbol-only font; and I highly suspect that when you choose that font, in fact ~all glyphs that you see come from some other substituted font; and when you see the “strange looking characters” in the list of fonts, that’s because in that list, no substitution is made.
