Ah. For this you should use FolderItem.GetSaveInfo. To store the

returns "text".
Would you recommend doing this when storing all strings in a text
file?
As I understand it, RB automatically uses UTF8 encoding when
writing strings
to text files, does that handle all kinds of unicode text?
Reading/writing text files was so easy back in the days when ASCII
was the
only thing around...
Okay, let's distinguish between "strings" and 'text". Here, a
"string" is a chunk of binary data. REALbasic String objects can
contain anything. "Text" is a string, plus a text encoding that
defines how to interpret the bytes.
FolderItem.GetSaveInfo returns a REALbasic string with nil encoding.
Thus it is not "text". What EncodeBase64 does is to take binary data
and encode it as an ASCII string. There is a Base64 class on my web
site if you want to see how it works.
If you have a REALbasic string that is UTF-8 encoded, it is "text".
If this text contains linebreaks, then you still need to consider
this when writing to and reading from files using TextOutputStream
and TextInputStream.
