/**
 * sentry-native
 *
 * sentry-native is a C client to send events to native from
 * C and C++ applications.  It can work together with breakpad/crashpad
 * but also send events on its own.
 *
 * NOTE on encodings:
 *
 * Sentry will assume an encoding of UTF-8 for all string data that is captured
 * and being sent to sentry as an Event.
 * All the functions that are dealing with *paths* will assume an OS-specific
 * encoding. Concretely:
 * - UTF-8 on macOS (at least on the versions the Native SDK supports)
 * - very likely UTF-8 on Android since it defaults to UTF-8 everywhere
 * - the locale encoding on Linux and other UNIXes
 * While the above are configurable, they consistently use the encoding along
 * the entire path processing allowing us to consider paths as almost entirely
 * opaque. On Windows, the situation is much more complex. This is because
 * Windows has
 * - locale-dependent multibyte encoding in the CRT,
 * - ANSI codepage-dependent multibyte encoding in the console and against the
 *   A-functions of the Win32 API,
 * - which can be configured independently by the application but also on the
 *   system level.
 * The above makes it very hard for us to track which kind of encoding to
 * expect (and often it isn't clear to the application developer either).
 * Moreover, in contrast to the UNIXes at certain points we have to make the
 * call (consider logging and serialization/persistence of paths as well as when
 * handling paths of modules and when symbolizing stack frames).
 * Thus, on Windows the Native SDK canonicalizes narrow character strings for
 * paths to be UTF-8 to prevent any ANSI code-page dependency. We also provide
 * public wide string APIs for paths, which we recommend if your narrow string
 * paths are not guaranteed to be UTF-8 encoded. Internally, we handle all
 * Windows paths as UTF-8 and only convert them to wide string if required
 * at the Win32 boundary (any of W-functions, we only use those) of the SDK.
 *
 * NOTE on attachments:
 *
 * Attachments are read lazily at the time of `sentry_capture_event`,
 * `sentry_capture_event_with_scope`, or at the time of a hard crash. Relative
 * attachment paths will be resolved according to the current working directory
 * at the time of envelope creation. When adding and removing attachments, they
 * are matched according to their given `path`. No normalization is performed.
 * When using the `crashpad` backend on macOS, the list of attachments that will
 * be added at the time of a hard crash will be frozen at the time of
 * `sentry_init`, and later modifications will not be reflected.

 *  - if you have a `before_send` implementation but only want to handle normal
 *    events with it, then you can define an `on_crash` callback that returns
 *    the passed-in event and does nothing else
 *  - if you are not interested in normal events, but only want to act on
 *    crashes (within the limits mentioned below), then only define an
 *    `on_crash` callback with the option to filter (on all backends) or enrich
 *    (only inproc) the crash event
 *
