NOTATIO

Ah: I see the confusion. OpenType can contain Type 1 PostScript data, but the font format itself is OK.

It's only the original 1980s Type 1 LWFN fonts, which have separate files for printer and for screen, that are on their way out.

Type 1s are the original 1980s PostScript fonts, with a separate file for screen bitmaps.

OTF fonts still contain PostScript data, they just dispense with the need for separate screen and printer files; and they can hold 1000s of characters.

OK, so I have basically understood nothing.
Shall I convert my font to another OTF type, benwiggy?

Glancing at a random OCTOwah.otf posted in 2015, it looks like the format should be fine.

It's an OpenType font with CFF/PostScript outlines. Being more pedantic, the outlines are cubic Bézier curves (TrueType outlines are quadratic Bézier curves); an OpenType font can also include those types of outlines. There's the unfortunate confusion that some may have referred to them as Type 1 OpenType (though no one I know does, today).

The name table in that 2015 OCTOwah.otf was missing a version field, but perhaps that was an old version.

No. OTF fonts are perfectly fine. OpenType is a more modern format, the lovechild of PostScript and TrueType.

The only fonts that are affected are the 'original' Mac typefaces with separate printer and screen files. On Windows, they have .pfb and .pfa extensions.
