Just installed and have to head out, I will test later today.
So far the only concern I have is the soon death of Type 1 fonts. We have many hundreds (thousands?) of them used all over the place. Not all have equivalents in OTF or TTF. Of course, converting is always an option but tedious when you're talking about thousands of files across 30 or so folders. We have fonts in alphabetical folders according to name, plus a few special folders for other groups, so filtering all those and feeding them into a font converter will be a large task plus the problem of dealing with ones that don't convert automatically and need to be loaded individually into Font Forge or something equivalent and manually rebuilt. It was bad enough when Adobe decided to drop support, at least we still could use them in Draw, now that's not going to be an option either.
For now it seems support is there, any hint on when it will be removed?
I'm kind of surprised Microsoft hasn't already removed the ability to install/use Postscript Type 1 fonts in Windows 11. The fonts still work for now. It's possible Type 1 font support could be removed in the upcoming Win 11 24H2 release. Or it may happen with the Windows 12 release late next year. IIRC official support for Windows 10 ends in 2025. At any rate, the clock is ticking on those old Type 1 fonts.
The interesting thing to me is that we have no idea what features in type one fonts we will lose!
I did a little more looking into this and it's apparently they don't feel like (aka spend money) supporting type 1 because browsers and mobile devices don't support them. Seriously. Wow, who cares? Browser and mobile support has absolutely no impact on me, OK whatever, guess I'll have to deal with it and convert all those fonts.
FWIW, I know lurking in our files going back nearly 35 years now, there's some multiple master fonts used. Since I know those went by the wayside long ago, I have a windows 98 virtual machine I can boot up with a copy of Draw v8 (yes 8 not 18) installed with Adobe Type Manager to use those multiple master fonts. Luckily they weren't used in a lot of things because they were a pain back then and still are.
But if performance in type manager is improved, that will be a bonus for sure.
One of the biggest factors killing support of Postscript Type 1 fonts is Harfbuzz. It's a software library used for "text shaping" a wide variety of alphabets. Anyway, Type 1 fonts are not supported by Harfbuzz. The text shaping engine is being adopted by a growing number of software applications. Adobe ditched T1 font support in its applications specifically so it could incorporate Harfbuzz.
Type 1 fonts are pretty limited. Each font requires two or three separate files. The fonts are limited to no more than 256 glyphs. A single static OpenType font file can easily do the work of several separate Type 1 fonts. With OpenType you don't need things like separate files for small capitals or "expert set" ligatures. Those features can be included in the same base OpenType file as alternate glyphs or character sets.
Still, I'd rather just convert certain old T1 fonts to OTF rather than buy entirely new versions of them. I have a number of Berthold "BE" fonts from ancient versions of Adobe Illustrator, such as the entire Akzidenz Grotesk family. That family costs over $1000 to buy "brand new" again in OTF format.
The OpenType Variable standard has resurrected the concepts in the dead T1 Multiple Master and TrueType GX font formats. OTF Variable has already been around for several years and is now vastly more successful than the T1 MM format ever was. Few vendors outside Adobe bothered developing T1 MM fonts. Dozens of different foundries are authoring OTF Variable fonts. Adobe has done OTF Variable re-creations of some of its old T1 MM fonts, such as Kepler and made them available thru their Adobe Fonts service. But some other interesting ones, such as Neuva and Penumbra are either available only in "static" form or are just not available at all.
Well, their pumping the bucks everywhere they can! Bobby, you put me on to a conversion software a few years back and I spent some time and converted everything I had. If I remember correctly, I even opened and resaved some problematic TTF fonts and CorelDRAW and the CFM run better. I still only use CFM as a font viewer.
After the 27th I'll have to experiment a bit testing the web/cloud process. I'll work out as many bugs as I can before my old laptop kicks the bucket.
That's another plus about TransType, it can repair some ill-behaved fonts. The app can also make larger type families behave properly with their naming conventions, so all styles appear in the same drop down menu rather than be scattered in two or more different groups.
