8  strings, compiled as a separate library. There are no new features in the 8-bit  strings, compiled as a separate library. There are a few changes to the
9  library, but some bugs have been mended. However, note that the pcre_info()  8-bit library, in addition to some bug fixes.

14    . When a compiled pattern was saved to a file and later reloaded on a host
15      with different endianness, PCRE used automatically to swap the bytes in some
16      of the data fields. With the advent of the 16-bit library, where more of this
17      swapping is needed, it is no longer done automatically. Instead, the bad
18      endianness is detected and a specific error is given. The user can then call
19      a new function called pcre_pattern_to_host_byte_order() (or an equivalent
20      16-bit function) to do the swap.
21    
22    . In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode
23      code points and are now faulted. (They are the so-called "surrogates"
24      that are reserved for coding high values in UTF-16.)
