URW DIN problems with the Polish characters

Hello everyone, I have a problem with wrongly displayed fonts in Safari in the Q&A section of e-learning I prepared in Captivate. I had to use Din Pro as company fonts there are not in Adobe Fonts. As an exercise, we used fonts from Adobe Fonts caled URW DIN, but we have the problems with the Polish characters "Ł, Ą, Ś, Ć, Ż, ź" see the attachment. This mistake occurs when these two letters appear next to each other "ŁĄ". Thank you in advance for your help.
