Question regarding "HL"

Hi,

when I create a new font, it contains as Verndor “HL”.
Is this ok? Can I use this?
Or are there any problems?

Best regards
Bernd

Yes, you can use it, it is a default ID that identifies fonts made with Font Creator. You are free to use your own Vendor ID. You could claim/ register a four-letter Vendor ID here:
