The wLcdLayout field is a number value from the CCID USB descriptor:
The majority (93,31%) of readers do not have a display so 0 lines and 0 characters per line.
We then have pinpad readers with a display. The most common configurations are 2 lines of 12, 16 or 17 characters.
One reader, VASCO DP865, has a big display with 8 lines and 24 characters per line.

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
