* libguile/fports.c (scm_open_file): Call consume-byte-order-mark if we
  are opening a file in "r" mode.

  byte-order marks.

  the value was not a struct.

* module/system/base/compile.scm (find-language-joint): Default to
  joining at the target language.

d7cb7f7925 weak-table consolidation around scm_i_register_weak_gc_callback
* libguile/weak-table.c (GC_move_disappearing_link)
  (move_disappearing_links): Factor out stub, as in previous weak-set
  commit.
  (resize_table): As in weak-set commit, finalizers do not run within
  allocators.
  (do_vacuum_weak_table): Add comment about need for trylock.
  (scm_c_make_weak_table): Use the new scm_i_register_weak_gc_callback.
  Previously this was the case because of a mistyped check for a
  "HAVE_GC_TABLE_START_CALLBACK" symbol, whereas the symbol was actually
  HAVE_GC_SET_START_CALLBACK.  Anyway, it's better to call this after GC
  anyway, as vacuuming might need to allocate weak links (on pre-7.3
  libgc without GC_move_disappearing_link) or reallocate the backing
  vector.

a0551390d5 consolidate scm_i_register_weak_gc_callback, update weak-set to fit
* libguile/finalizers.h:
* libguile/finalizers.c (scm_i_register_weak_gc_callback): New internal
  helper, from weak-set.c.

  Relative to the previous weak-set.c version, prefer the
  finalizer-based implementation.  Fix bug regarding confusion between
  scm_before_gc_c_hook and scm_after_gc_hook.  Fix bug regarding
  referencing weak values outside of the alloc lock.

* libguile/weak-set.c (GC_move_disappearing_link): New stub.
  GC_move_disappearing_link is only available in libgc 7.3.
  (move_weak_entry): Use the new stub instead of ifdeffery.
  (resize_set): Now that we run finalizers from a separate thread or
  async, we can keep the lock while reallocating the set vector.
  (do_vacuum_weak_set): For the same reason, always lock the set.
  Remove implementation of scm_c_register_weak_gc_callback in preference
  of the new copy in finalizers.c.
  (scm_c_make_weak_set): Use the new scm_i_register_weak_gc_callback.

  GC_get_free_space_divisor, and GC_set_finalize_on_demand.  Remove code
  in the case in which we did not have GC_set_start_callback.

449ca87bdb ASCII is not ISO-8859-1

  ASCII is not the same as ISO-8859-1, because it does not allow
  characters above 128.  Fix this.

93c4fa2174 Port encodings are case-insensitive, but normalized to upper-case.
* libguile/ports.c (ascii_toupper, encoding_matches)
  (canonicalize_encoding): New helpers.

  (scm_c_make_port_with_encoding):
  (scm_i_set_default_port_encoding):
  (scm_i_set_port_encoding_x): Use the new helpers to be
  case-insensitive and also to canonicalize the internal representation
  to upper-case ASCII names.

  (scm_i_default_port_encoding): Never return NULL.
  (scm_port_encoding): The encoding is always a string.

* libguile/read.c (scm_i_scan_for_encoding): Use a locale-independent
  check instead of isalnum.  Don't upcase the result: the port code will
  handle that.

* test-suite/tests/web-response.test ("example-1"): Adapt test to expect
  normalized (upper-case) encoding for the response port.

8c76a8971b fix bug where scm_from_utf8_stringn would not detect bad utf-8
* libguile/strings.c (scm_from_utf8_stringn):
* libguile/symbols.c (utf8_string_equals_wide_string): The "bad UTF8"
  return from u8_mbtouc is a 0xfffd character, not a negative byte
  length.  Fixes a bug in which invalid UTF-8 would not be caught.

* libguile/bytevectors.c (scm_utf8_to_string): Use scm_from_utf8_stringn
  directly.  Just a little cleanup.
