Summary: The default behaviour of rocksdb is to use the `*A(` windows API functions. These accept filenames in the currently configured system encoding, be it Latin 1, utf8 or whatever. If the Application intends to completely work with utf8 strings internally, converting these to that codepage properly isn't even always possible. Thus this patch adds a switch to use the `*W(` functions, which accept UTF-16 filenames, and uses C++11 features to translate the UTF8 containing std::string to an UTF16 containing std::wstring. This feature is a compile time options, that can be enabled by setting `WITH_WINDOWS_UTF8_FILENAMES` to true.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.
