>What obscure features?  Specifically.

One I know of is the cursor positioning escape sequence.  CSI Pr ; Pc H
where Pr and Pc are ASCII decimal numbers for row and column.
(CSI is <ESC> [ or the 8 bit equivalent) When Pr and Pc are both specified
it works. However, the spec states that if either Pr or Pc are omitted (or
specified as 0), it is treated as if it was 1.  You can also omit the ";"
if you omit Pc.  So the sequence CSI ; 7 H goes to Row 1, Column 7, and 
both CSI 7 ; H and CSI 7 H goes to Row 7, Col 1, and CSI H goes to Row 1, 
Column 1.  Some emulators don't do this right, and I've seen editors use 
the shortened sequences.

Generally I haven't investigated the details, rather I see if the output 
of a few tools on VMS work correctly.  (I figure just about everyone here
other than JF isn't familiar with VMS).  Specifically, two VMS editors
($ EDIT/EDT and EDIT/TPU), Notes and $ SHOW CLUSTER are usually enough to
scare out a bug or two, or show whether the keypad works correctly.

Somewhere on the net is a system you can telnet/SSH to and it exercizes
just about every VTxxx function possible, and supposedly almost no
emulators get everything (not counting non-applicable things like 
initialize selftest) right.  It even knows of VTxxx bugs and you can
tell if your emulator is bug-for-bug compatible.  I'll have to find it
again, hope it still exists.  Haven't used it in years.
