Enhancement: adjust mathbb letter weight

[grivasgervilla]

Hi, first of all, I think that STIX is one of the best fonts for scientific texts, and it should be the standard in the future.

I am not a font designer, so I may be wrong, but I think that the weight for the mathbb characters does not match with the rest of the font glyphs.

In the previous example it could be seen that the \mathbb{C} character, ℂ, has a different weight from the rest of glyphs in the image.

Many thanks for your time.

This is the designed weight of the double-struck characters, which are constructed from a mostly monolinear stroke weight, and in which the enclosed areas between the strokes represents the struck-out portion of the letter. This makes them naturally lighter structure than the other letters. If you imagine the struck-out portion being filled in, then they would be similar weight:

Thanks for your quick answer, I see your point and I will close the issue.

Thanks for your time and your font.
