Describe the bug

I try to catch exception with Sentry.capture_exception but occured Encoding::UndefinedConversionError.
After investigating, the error occurred because it contained an escaped string such as \ xE3 in event_hash.

error log

Unable to record event with remote Sentry server (Encoding::UndefinedConversionError - "\xE5" from ASCII-8BIT to UTF-8)

To Reproduce
request string include an escaped string such as \ xE3, \xE5.

Expected behavior
I`d like to avoid the error even if it contains escaped strings.

Actual behavior
occur Encoding::UndefinedConversionError - "\xE5" from ASCII-8BIT to UTF-8 if event_hash contain escaped string such as \ xE3, \xE5.

Environment
