IIRC Lucida in Y&Y TeX used TeX‘n’ANSI encoding by default (TS1?), or
at least T1 -- but certainly not the old OT1, which makes it less
surprising that it worked, because the alternative font encodings try
to follow US-ASCII much more closely. People writing Spanish texts
might get a nasty surprise though.

Something $>$ something else. or even $\text{something} > \text {something else}$. This even makes it easier to translate $>$ into $\rightarrow$, which probably is even clearer (was something bigger
than something else, or did something lead to or turn into something
else?)

Don't blame Donald Knuth for starting on TeX before many of the
standards we take for granted today were finalised. The more modern
font encoding vectors in TeX map more closely to what many expect. To
avoid breaking the old documents, it is however not really possible
to completely replace OT1 by T1.

You're not the first one to be pleasantly surprised.
