description: >
  When using ROM pointer compression ROM pointers are compressed to the
  integer range [DUK_USE_ROM_PTRCOMP_FIRST,0xffff].  The default value
  allows for 2048 ROM pointers, which can point to objects and strings.

  You may need to lower this value to support more pointers if there are
  a lot of custom ROM strings/objects.
