I would like to be able to use this font when I'm not using LaTeX, is that possible? Is it available somewhere? Which is its name?

Thank you very much.

It's the second one of the table suggested by Claude, cmbsy10, not eusm10, I think...

rocamaco is right, its the uppercase characters of cmbsy10

Identified font: cmbsy10

Thank you rocamaco

You made my day
