Some ID3v2.4.0 frames such as text information frames support multiple strings
separated by the termination code of the character encoding. If the encoding
is $01 UTF-16 with BOM, all strings shall have the same byte order. In the
multi strings written by TagLib, all string elements of such a multi string
have a BOM. However, I have often seen tags where a BOM exists only at the
beginning, i.e. at the start of the first string. In such a case, TagLib will
only return a list with the first string and a second empty string. This
commit will detect such cases and parse the strings without BOM according to
the BOM of the first string.
* clang-tidy: replace static_cast with dynamic_cast

* use std::pair instead of 2D C array
Mostly the same. Except there's now an association between both values.
make_pair has to be used since there's no uniform initialization.

The while loop in this function assumes that `data.end() - 1` is less
than `data.end()`, which isn't the case if `data` is empty since
`data.end()` can be a nullptr.
The support for MusicBrainz properties is enhanced with "ARTISTS", "ASIN",
"RELEASECOUNTRY", "RELEASESTATUS", "RELEASETYPE", "MUSICBRAINZ_RELEASETRACKID",
"ORIGINALDATE" on APE, ASF, MP4, ID3v2, and Xiph tags.
For an ID3v2 "DJMIXER" property, the "DJ-MIX" TIPL role must be used.
For an ID3v2 "MIXER" property, the "MIX" TIPL role must be used.
Otherwise it will not work when reading the tag and creating
properties from the wrong TIPL roles.
As described in id3v2.3.0.txt (4.2.1, TCON), multiple genres are
only possible as references to ID3v1 genres with an optional
refinement as a text. When downgrading multiple genres from
ID3v2.4.0, they are now converted to numbers when possible and
the first genre text without ID3v1 reference is added as a
refinement. The keywords RX and CR are supported too.
This creates symetry with ID3v2::Tag::comment() in preferring frames with no description
when choosing which COMM frame should be updated. (Previously setComment() simply updated
the first COMM frame.)
Fixes#950
I'd imagined it being useful for calls to `strip()`, but it's not
actually used there since that's an OR-ed together set of flags
representing which tags to strip.
This does not put the deprecated marker on methods that will or could resolve
to the same overload, e.g.:
void foo(bool bar = true); // <-- not marked
void foo(Bar bar) // <-- since this will have a default argument in the new version
This uses explicit enums for e.g. the ID3v2 version, making calls more
readable:
file.save(ID3v1 | ID3v2, StripOthers, ID3v2::v4, Duplicate);
Instead of:
file.save(ID3v1 | ID3v2, true, 4, true);
Needs to be ported to other types, per #922
