Pangrams were pure wordplays, that because of IT has become a nice tool to test keyboard and fonts, assuming they are easy to remember and short. Therefore perfect pangrams are so nice: you don't need to repeat any character (with the exception of the space).
I've looked on the list of pangrams and I've noticed that most of them are either not perfect or are heavily using acronyms, initials, own names etc. (which I call not "honest", because it's a bit cheating).
Those "honest" looked like a gibberish for me:
Jink cwm, zag veldt, fob qursh pyx
However, those are real English words, only I doubt a bit, a regular native speaker would understand them. So 2 questions arise:
1) Are such pangrams as above understandable for a regular English native speaker?
2) If not, are there any others that would be perfect, honest (no acronyms, exotic own names etc.) and written with commonly known words?
Just to give some context, the Polish perfect pangram
Mężny bądź, chroń pułk twój i sześć flag.
would be understood by any native speaker, and it makes perfectly sense (be brave, protect your regiment and six flags). It's a poetry masterpiece, you can say.
