Infinality (v38) was substituted by v40 in 2.13.1. Anybody requesting
v38 got v40 instead... and nobody even noticed. That is the whole
point of the exercise: v40 is perfectly capable and better than just
good enough. Now the code is physically gone for good. It is much
better to improve faster and lighter v40 moving forward than dwelling
on unmaintained, poorly understood, and riddled with exceptions v38.

Why? Or, more precisely, why do you think that either v38 or v40 were
ever designed to mimic the corresponding versions of Microsoft engine?
That was never the case. *Both* of FreeType implementations were based
on principles described in
https://learn.microsoft.com/en-us/typography/cleartype/truetypecleartype.
Both! but neither was actually tested to reproduce Microsoft
precisely. Much like we have no idea how Microsoft does ClearType
filtering, except for some public papers. If anybody, Adobe helped
here a lot more. Microsoft is multisampling for antialiasing, we
don't. Therefore, FreeType != Microsoft in any sense, including v38 !=
38 (GETINFO version).

No, there isn't.  Why do you need that?

You can either use `FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY` and/or
`FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY` to enforce the old
four-faces-per-family scheme, or you can parse the 'name' table by
yourself, see `FT_Get_Sfnt_Name`.

Hello,

Looking more closely at code I think freetype is returning preferred Family 
name of font as font family if that is present inside font.
Is there anyway to know if the font name is picked from preferred Family name 
or Family only.

Thanks,

Hi ,

I am using FT_FaceRec_ object to get the font family name in my code. But not 
getting the correct (entire font name as family name) for few fonts.
For e.g. Arial Black .Freetype is returning font name as Arial and Style as 
Black.
On further looking at code I found it goes into the check for 
TYPOGRAPHIC_FAMILY and return the valid string as Arial and
didn't execute the condition with FONT_FAMILY.
Is there is any way I can know if the font family name  has TYPOGRAPHIC_FAMILY 
or FONT_FAMILY.

Thanks,
