Code 128 internal error when unused ^NNN under some conditions

[semireg]

There seems to be an issue when unrecognized (unparsed?) ^NNN are encountered, but not "enabled" via parse option(s). This should probably fail gracefully by just rendering the ^NNN. I wrote "options" plural because I thought I could trigger this error with a different combination of parse/parsefnc... but looks like this is all I can reproduce for now.

TypeError: undefined is not an object (evaluating 's.length')
