If you've already developed a speculative fix, I could test it.
(I could try hacking this commit myself
  
https://github.com/wxWidgets/wxWidgets/commit/e5e92c92ce5982662cb6c5dfd0f355ddb075da47
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.

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

]$</dev/clipboard od -t a
0000000   C   :   \   o   p   t   \   l   m   i   \   e   r   a   s   e
0000020   m   e   \   q   u   o   t   e   -   v   o   l   -   n   o   n
0000040   v   a   r   .   c   n   s
0000047
/opt/lmi/data[0]$</dev/clipboard od -t a
0000000   C   :   \   o   p   t   \   l   m   i   \   t   e   s   t   \
0000020   s   e   q   .   c   n   s
0000027

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.
