Hi Ticker,

yes, thanks, that was the problem. The table width also depends on this and I didn't understand that so far.

Hi Gerd

I'm looking at GPXSee at the moment.

Significant to the problem lots of symbols:

The size of the tab1 offset into the symbol list is the same as the

size of the size (the 1+ bytes after the 8/symbol width), so, if more

than 127, it needs an extra byte.

Hi Ticker,

yes, one byte at a time. Else we would need symbol width > 8, and

Garmin doesn't use that for the unicode maps that I know.to

I plan to contact the author of GPXsee, Martin Tůma. He seems to know

much more than we do and maybe he is willing to help.
