Hi dine, I considered this issue back in the day as package maintainer.
In the United States and some other jurisdictions, possibly not including Japan[1], bitmap typefaces are not regarded as copyrightable. In fact, typefaces generally aren't--but the "font" that creates them in the form of instructions in a sort of programming language, often are. As I understand it, in the West the reasoning is based on analogy to and the precedent of hot-metal typography, whereby you could purchase a "font" from some foundry and rack it in your Linotype, for example. By contrast, if a person studied a font in a newspaper or book closely and cast his own hot-metal font to simulate it, that person enjoyed independent commercial rights. Donald Knuth, for example, famously designed the Computer Modern fonts based on reference to typefaces traditionally used in mathematical typesetting. Let me know if you have further questions or if this fails to illuminate the issue. Regards, Branden [1] I did some limited research on this potential exception. It seemed to involve only glyphs used in Japanese typography (hirigana, katakana, and kanji) and explicitly _not_ Western scripts (romaji). At the time, the Lucida fonts didn't have renderings for any of these codepoints, and my guess would be that they still don't, as my recollection is that those fonts have been close to moribund ever since they landed in the X Window System distribution. Maybe the Euro sign got added, and I wouldn't count on much more than that. Scalable fonts have been where the action is for over 25 years. The bottom line is that we had no bitmap fonts with "Japanese characters" with a non-free license, and no bitmap fonts without them that had a license that was binding.

Does Lucida need similar treatment?
