# stix and stix2 fonts

Support for type-1 version of stix2 fonts just came out. I think it is a quite nice font.

However it seems that for stix2 fewer math alphabets are available than for stix (old version)

For instance:

If I use

``````\usepackage{stix}
\usepacakge{bm}
``````

from

``````\$\bm{\mathbb{C}}\$
``````

I do get a boldface \mathbb C BUT

if I use

``````\usepackage{stix2}
\usepacakge{bm}
``````

from the same command I do not get a boldface letter.

Indeed, in the documentation I see that in stix math alphabet \mathbfbb was defined but in stix2 it is not.

Anyone knows what is the situation about stix2?

Thanks Maurizio

• There are no bold blackboard symbols in unicode, so imho you are out of look and you won't find them in stix2. Apr 21, 2018 at 13:25
• Thanks. But I thought I would find bold mathbb since in stix (earlier version) it was there. Why to take it away?

The `\mathbb` is the blackboard bold font. I am not sure why do you need a bold version of a bold font.
