8-bit and 16-bit and 32-bit export

[Pyanepsion]

Hello everyone. Unicode offers 8-bit, 16-bit and 32-bit font formats. Older formats are not always recognized.
For example, the symbol.ttf font provided free by Microsoft with Windows is a font which displays correctly in FontCreator, but does not display correctly with the Firefox software because it is an 8-bit font and Firefox does not understand the principles of Unicode.
How to convert a font to 8 bits, 16 bits or 32 bits?
Thank you for your explanations.

It seems you are talking about the 8-bit, 16-bit, and 32-bit Unicode Transformation Formats, but those are not related to font formats.

symbol.ttf is a font with a Symbol encoding id. Maybe that is the issue, but it might help if you better explain the issue.

It might help if you convert from Symbol to Unicode, which is an option in FontCreator. From the main menu select Tools -> Convert Font -> Convert to Unicode Font.

Thanks Erwin. My main concern was indeed that the symbol.ttf font was not recognized by the Firefox browser. The FontCreator conversion tool now allows it to be displayed as shown in this draught.

Firefox is, of course, primarily an Internet browser and PDF viewing is only a secondary function, but the Symbol font is one of the 14 fonts that all PDF viewers should be able to display according to the ISO 32000-1: 2008 standard.

It seems that the problem has been around for a long time, but the discussion of the Firefox bug report seems rather smoky.

I would like to find out how to display such fonts in Firefox without having to install the font conversion on the website. On Edge, and Chrome, the display is fine.
