BBBike.org map extracts

[ianchapp]

Since the demise of openstreetmap.nl, I've been trying BBBike.org to get Garmin maps of more obscure areas, in this case, Morocco.

https://extract.bbbike.org/

BBBike.org works brilliantly, except that I have the choice of Latin1 or UTF-8 character sets. I suspect I need UTF-8 (maybe as some Arabic characters?) but unfortuantely when I start my Zumo XT with a UTF-8 IMG file, I get a message that the file is corrupt and unusable.

So Latin1 works, but most place names are appended with a large number of ????? question marks etc, which is extremely annoying!

Anyone have any experience or suggestions?

This issue is hinted at, halfway down this page in bold text. But no solution!
