Does the DOS version have an apostrophe?

Yes the DOS version also has an apostrophe.

Fixed in check-in 253, this will be in build 1.0.16

By the way, this typo also occurs in view => items, view => spells (can search 
for
"spells in memory"), magic => cast, magic => memorize (can search for "spells in
grimoire"). The game crashes with respect to trying to scribe scrolls, but I 
would
imagine the same typo occurs there (can search for "spells on scrolls"). I've 
checked
that those appear correctly (for example, "<char>'s spells in memory") in the 
DOS
version.

All those code paths use the same block of code, so will be all fixed in the 
next build
