oh, i forgot to mention... and before i close the browser tabs to it.. i found some really good explanations of what encodings actually are, and how they got so complicated over time.. https://www.joelonsoftware.com/2003/10/08/the-absolute-minimum-every-software-developer-absolutely-positively-must-know-about-unicode-and-character-sets-no-excuses/ https://kunststube.net/encoding/ https://kunststube.net/frontback/ On Sun, Nov 22, 2020 at 8:24 AM Rene Veerman < rene.veerman.netherlands@gmail.com> wrote: > ok.. because it was googling and reading up on open source documents > describing encodings and how to deal with them in general that led me to > this solution, i thought it would be nice for me to share my code on how to > parse email data.. > this includes the complete fix for the problem which started this thread, > in getPart(), switch($encoding) case 0: > > i'll let you all know if i run into any more special cases, and the > (eventual) solutions to those.. > this code will be part of my > https://github.com/nicerapp/nicerapp > opensource CMS, which is available to the public for 10% of the profits you > make with it. > > i'll consider making the webmail part of it LGPL (true > opensource available for commercial use without cost). > > bye for now, and thanks for being the mirror i needed to get this solved :) > > function webmail_get_mail_content ($serverConfig, $serverIdx, $mailboxes, > $mailboxIdx, $mailIdx) { > $c = $serverConfig;
