I am struggling with a problem I can't even name properly: I'm writing an article about an object A as well as its slightly different variant A'. I am wondering what character/symbol and/or spacing magic I need for the '.
I started by simply using ' but this gives me an pretty nasty space between the A and the '. Then I tried to correct that with A\kern-0.1em'
Unfortunately this is not consistent as things get stretched around to fill the page (in some cases there's just as much space as without kerning).
I also read through the giant symbol archive but at a glance I couldn't find anything appropriate. Well, I didn't know what I'm looking for so maybe I missed it. Surely this type of notation is quite common?
Is there any better way to achieve this? Honestly I don't even know if an apostrophe is the right kind of dash for this kind of labeling. So any suggestions for coding magic or new symbols are welcome.
Many thanks.
A\kern-1.7pt'
. Each letter will, in general, require a different kerning. Something similar in math mode:$\mathrm{A\!}'$
