This can be useful on certain platforms that do not provide the standard iostreams, such as certain embedded systems.

## Fallback stringifier
|
||||
|
||||
By default Catch's stringification machinery falls back to a "{?}". To
|
||||
let projects reuse their own existing stringification machinery, this
|
||||
fallback can be overriden by defining `CATCH_CONFIG_FALLBACK_STRINGIFIER`
|
||||
to a name of a function that should perform the stringification instead.
|
||||
|
||||
The provided function must return std::string and must accept any type
|
||||
(e.g. via overloading).
|
||||
|
||||
_Note that if the provided function does not handle a type and this type
|
||||
requires to be stringified, the compilation will fail._
