I this message:
...I sent an attachment to a list with this file name:
1983, Potgieter en Prozesky, 8 pages - Verklarende woordelys van terme in die molekulêre biologie
and the attachment's link is broken.
In the mail that I received in my e-mail program, I see this in the footer:
en Prozesky, 8 pages - Verklarende woordelys van terme in die molekul�re biologie.pdf: https://groups.io/g/zalang/attachment/65905/2
The character ê is not that unusual. Surely this wouldn't be the problem?
