For values of "several" up to 16, you might want to look at VFAE.
I haven't had a chance to use it yet, but it's on my list of vector
instructions potentially useful for general coding.

Branching and looping are expensive, so for scanning more than
one byte, I would always use TRT for more than one target value
and in most cases I would use SRST for a

Given several target characters, at what value of "several" is the
break-even between TRT and a chain of CLI; BC?
(It's probably model-dependent.)
The CLI chain might be optimized by CLI first for the median value and
using the outcome to bypass half the remaining tests.
