Comment 3 prgmgr 2003-10-30 21:01:40 UTC 
mehlng, does this problem still exist in OOo 1.1.0?
Comment 4 mehlng 2003-11-11 09:06:53 UTC 
Yes it's still there.
Formula is neutural object, see attached file.

SBA: Target set to OOo 2.0
Comment 6 l_k 2003-12-31 13:48:05 UTC 
It seems that formula should be treated as a neutral character:

http://www.unicode.org/reports/tr9/tr9-10.html#Bidirectional_Character_Types:
"For the purpose of the bidirectional algorithm, inline objects ... are 
treated as if they are an OBJECT REPLACEMENT CHARACTER (U+FFFC)."

http://www.unicode.org/Public/UNIDATA/UnicodeData.txt:
"FFFC;OBJECT REPLACEMENT CHARACTER;So;0;ON;;;;;N;;;;;"
Comment 7 mehlng 2004-01-01 19:23:56 UTC 
It may be so in the specs however the sad reality doesn't work like that.
Think of:
FORMULA f(x), f(y)
will be rendered as
f(y) f(x), ALUMROF

which is clearly wrong.
Comment 8 stefan.baltzer 2004-02-06 17:15:24 UTC 
SBA-> Mehleng: In the document, you say that deleting "THE" A will make the line
RTL.
I tried several "As" in that line but I couldn't reproduce this in Build 645m27-s1. 
Please comment.
Comment 9 mehlng 2004-02-15 08:51:14 UTC 
indeed I cannot reproduce this as well.
The formulas are indeed neutural objects but I'm not sure this is wrong.
I'm closing this issue.

SBA: Thanks. Closed as worksforme based on submitters comment.
