OK that is clear.

\show for the commands

\t
\c
\v
\b
\d
\u

gave this output

> \t=macro:
->\OML-cmd \t \OML\t .
l.4 \show\t


> \c=macro:
->\OT1-cmd \c \OT1\c .
l.5 \show\c


> \v=macro:
->\OT1-cmd \v \OT1\v .
l.6 \show\v


> \b=macro:
->\OT1-cmd \b \OT1\b .
l.7 \show\b


> \d=macro:
->\OT1-cmd \d \OT1\d .
l.8 \show\d


> \u=macro:
->\OT1-cmd \u \OT1\u .
l.9 \show\u

So there is indeed something special with \t (\OML instead of \OT1) although
I have no clue what this means.
