welcome to the wonderful world of crossplatform development :-)
There is a difference between mac and win in the way text (strings) are
which is especially important in a language with umlauts and accents
I guess the text is created on a mac and "only" displayed on windows,
In that case you would have to convert the text from mac to ISO
encoding to display it correctly
I do something like this, since i also create text on my mac, but will
display it on windows, too...
I use this function to convert "mac" text for each according platform:
function mac_or_win tText
if the platform contains "Mac" then
## we are on a mac an can display the text without having to convert
## we are on win or *nix and so need to tranlate from Mac to ISO
And then i use it like:
put mac_or_win(line 1 to 3 of fld "mactext") into fld "display"
Hope that helps.
