[R] "read.table" and "scan" skips newlines which "count.fields" finds in Thai textfile

Hi there,

I have some problems reading in a Thai text.
Some of the newlines are skipped.

(see the contents of my file below)

R>count.fields ("my.txt",  sep='\n', quote="")
[1] 1 1 1

Three lines with one item each, right?

R> scan("my.txt", what="", sep="\t", quote="")
Read 2 items
[1] "犹\x83犧癌ケ\x88 犧\x84犧」犧ア犧\x9a\n犹\x83犧癌ケ\x88 犧\x84犹謂クー" 
[2] "犹\x83犧癌ケ\x88 犧\x84犧」犧ア犧\x9a\n"  

Two items. Note that arguments to "count.fields" and "scan" are the same.
There is a newline within the first item ("\n").

> read.table("my.txt", encoding="UTF-8", header=F, sep="\t", quote="")
[1] V1
<0 rows> (or 0-length row.names)

Zero items.
I just reduced my file to zero.

Needless to say, my editors show 3 lines (Vim, Em, Hidemaru)
Hex dump shows the newline chars clearly (see below).

I have seen related questions but not the solution: 

And just for fun : 
R>read.table("my.txt", encoding="justkidding")
[1] V1
<0 rows> (or 0-length row.names)

Its funny NOT to see any complaints about "justkidding" encoding...
(it is so not R-ish :-)

We are using R2.8 -> for a while we are stuck with it.
(I briefly installed R2.10 but did not seem to overcome the problem)

Any kind of help is greatly appreciated.



ps : replacing Thai with Japanese text (same utf-8) had slightly different
 (only some of the newlines were ignored)
