d1b9f8ace9 Port encodings cannot be NULL
* libguile/ports.c (scm_c_read_unlocked, scm_ungetc_unlocked):
* libguile/read.c (scm_read_character):
* libguile/vports.c (sf_fill_input): Port encodings cannot be NULL any
  more, now that encodings are canonicalized, so simplify these.

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.

  comment to mention codepoints.
  (scm_read_string): Make `str' a list of strings, instead of a string.
  Store characters read in buffer `c_str'.  Cons to STR when C_STR is
  full, and concatenate/reverse at the end.

  `char *' instead of `int'.  Allocate the overflow buffer with
  `scm_gc_malloc_pointerless' instead of `scm_malloc'.  Return either
  the overflow buffer or BUFFER.
  (scm_read_number, scm_read_mixed_case_symbol,
  scm_read_number_and_radix): Rename `buffer' to `local_buffer', and
  `overflow_buffer' to `buffer'.  Remove `overflow'.  Adjust code to new

043850d984 Unoptimize 'read' to return freshly allocated empty strings
* libguile/read.c (scm_read_string): Return a freshly allocated string
  every time, even for empty strings.  The motivation is to allow source
  properties to be added to all strings.  Previously, the shared global
  'scm_nullstr' was returned for empty strings.  Note that empty strings
  still share a common global 'null_stringbuf'.

* test-suite/tests/srfi-13.test (substring/shared): Fix tests to reflect
  the fact that empty string literals are no longer guaranteed to be
  'eq?' to each other.

d9527cfafd read-extended-symbol handles backslash better, including r6rs hex escapes
* libguile/read.c (scm_read_extended_symbol): Interpret '\' as an escape
  character.  Due to some historical oddities we have to support '\'
  before any character, but since we never emitted '\' in front of
  "normal" characters like 'x' we can interpret "\x..;" to be an R6RS
  hex escape.

* test-suite/tests/reader.test ("#{}#"): Add tests.

df941b5b62 Undeprecate read syntax for uniform complex vectors
* libguile/read.c (scm_read_sharp): Move the "#c..." case outside of
  #if SCM_ENABLE_DEPRECATED, and to the same section which handles
  "#s...", "#u..." and "#f...".
  Thanks to Andreas Rottmann <a.rottmann@gmx.at> for the bug report.
