How to use Unicode for filenames?
My application will be similar to raw-identity sample program.
Windows: use LibRaw::open
Windows: use LibRaw::open_file(wchar_t *)
macOS: LibRaw::open_file(char*) accepts UTF-8 filenames.
Other operating system: do not know :), you probably may need to implement own LibRaw datastream.

Thank you.
Thank you.
dcraw_ppm_tiff_writer has no unicode version
LibRaw::open_file(wchar_t *) has to be used to open a file having Unicode filename. But LibRaw::dcraw_ppm_tiff_writer has no unicode version. Am I supposed to write my own or is there a work around?
BTW: I am working under Windows and all filenames are Unicode.
Yes, ppm_tiff_writer is a
Yes, ppm_tiff_writer is a sample code only to allow LibRaw samples to write output files.
You may re-implement it, or use dcraw_mem_image() to create in-memory bitmap and save it using your own code.

dcraw_ppm_tiff_writer has no unicode version
The problem is that I use the LibRaw.dll and his C API (My code is written with Delphi). And there is no access [as far as I can see] to the data structure required to implement a tiff writer. So I have to implement it is C++ and expose the function in the C API dll. The final effect is that my application will have to use a special DLL. I don't like the idea.
IMO LibRaw should expose a complete unicode API which is standard nowadays.

LibRaw is open-source, we welcome contributions from other developers

contributions from other developers
OK, I understand. Sorry, I'm new to LibRaw.
If I do the changes/additions, will it be merged in the distribution for next revision?
My current work is to create a Delphi wrapper so that LibRaw can be easily used by Delphi developers. This wrapper will be open-source and made available in a GitHub repository (Or even better - if it is possible directly - in the LibRaw repository).
We are happy to accept
We are happy to accept additions if they do not violate the general ideology of the library and solve a problem of interest to more than one user.
Please use github pull requests for such a contributions.
Delphi/other language wrappers are out of our interest because we'll unable to support such improvements.
