/**
 * 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, typically ANSI on Windows, UTF-8 macOS, and the locale encoding on
 * Linux; and they provide wchar-compatible alternatives on Windows which are
 * preferred.
