If you've already developed a speculative fix, I could test it.
(I could try hacking this commit myself
to add an extra condition, but I don't know how wx differentiates
msw versions at run time.)

However, would it even be appropriate to change wx trunk for this?
Perhaps commit/e5e92c9... really was a useful improvement for msw-xp
users of right-to-left alphabets. And perhaps the reason why this
happens--on my machine only--is that I'm running in a VM with a
paravirtual graphics driver. You can't reproduce it, our end users
won't see it, and it's not an actual problem for me, so maybe we
should just drop it.

unmistakable here]

They all look perfect. I'll copy and paste a couple and run them
through 'od' just to be sure:

]$</dev/clipboard od -t a
0000000   C   :   \   o   p   t   \   l   m   i   \   e   r   a   s   e
0000020   m   e   \   q   u   o   t   e   -   v   o   l   -   n   o   n
0000040   v   a   r   .   c   n   s
/opt/lmi/data[0]$</dev/clipboard od -t a
0000000   C   :   \   o   p   t   \   l   m   i   \   t   e   s   t   \
0000020   s   e   q   .   c   n   s

They're exactly as I would expect: no 'LEFT-TO-RIGHT EMBEDDING'
(U+202A) character.

In "registry editor", I deleted all the keys I could, leaving only
"(default)" in lmi\ and lmi\lmi_wx, which resist deletion. Closing
"registry editor" and restarting lmi (which I had closed before
these deletions), I see the funny square character again.
