If it's a GTk+ bug then this bug should be available in all GTK+ apps. This 
bug (Typing English in xchat appears RTL when LANGUAGE=ar) is only available 
in xchat. Up to now, Ahmed khalifa's explanation of the paragraph level tends 
to be the most convincing. xchat need to calculate the paragraph level 
depending upon the input text not upon the env variables.

karouri, weak characters should have nothing to do with this bug because if 
the paragraph level is set to 0 the weak characters should appear properly, 
right?

After reading part of the BiDi algorithm, I need some answers to understand 
BiDi and Unicode better which will help in filing bugs later.

- Why do we have AL and R? what's the difference between right-to-left in 
Aabic and Hebrew?

- Why do we have characters such as Arabic full stop which is different than 
an English fullstop?

- I think the thread which spoke about a poor BiDi implementation ends in the 
conclusion it's not BiDi fault but implementation fault, if any, right? 
Karouri, do you think typing C++ in an Arabic contex which prints ++C is a 
bug? I personally thinks it's not but may be I didn't understood weak 
characters well, or you want a plug sign to be classified as a strong 
character which will cause more problems AFAIK.
