The conference paper (which is very well written and approachable) suggests that the precision of instruments was insufficient to establish this as of 20-ish years ago. See the section "First Experimentations": https://www.researchgate.net/profile/Unto-Laine/publication/380027668_Magneto-acoustic_triangulation_method_for_electric_discharge_localization_in_the_atmosphere/links/664e05d6bc86444c72f6c944/Magneto-acoustic-triangulation-method-for-electric-discharge-localization-in-the-atmosphere.pdf https://www.researchgate.net/profile/Unto-Laine/publication/...
Trivia: I tried to copy "First Experimentations" directly from the pdf and this what came out of my clipboard: -*%.$+/01/%*2/#$3$**&#. Thanks, Researchgate

- yorwba 2y agoSeveral chunks of text in that PDF start with the printable ASCII characters from ! onwards in order until there is a repetition, e.g. Magneto-acoustic triangulation from the headline corresponds to !"#$%&'(")'*+&,)-&.,"$#*/"&,'$ which is >>> list('!"#$%&\'(")\'*+&,)-&.,"$#*/"&,\'$'.encode('ascii')) [33, 34, 35, 36, 37, 38, 39, 40, 34, 41, 39, 42, 43, 38, 44, 41, 45, 38, 46, 44, 34, 36, 35, 42, 47, 34, 38, 44, 39, 36] So I think this is probably a PDF font-encoding issue that might've already affected the author's original upload.
- pierrec 2y agoYou're right, I immediately assumed some annoying DRM, but after looking it up, it does seem more like a bug. I couldn't find any clear explanation for why it happens though.
