John,
Look at UTR#20 and at UAX#9 (the 4.01. version is due out shortly).
Taken together they suggest that the non-plain text way is to keep such
text direction overrides out of band (i.e. in markup) and to apply the
bidi algorithm segment by segment in a marked up file.
If you export to plain text, follow Jony's suggestion, and when
importing text into a markup language environment, substitute
the equivalent markup (*) and remove the LRO/PDF from the data
stream.
It might be a while before applications really support this, but
you can always construct two text files, one in correct plain
text (using a span delimited by LRO and PDF) and one in correct
HTML, for example, and try and import/export them in and out and
across your favorite tools.
By all means, file as many bugs against them as you find ;-)
A./
(*) if available - this is a necessary caveat.
