Hi,

Unfortunately wmanaged_mapped_file constructors use char instead of wchar for the \
filename. This causes big problems on windows where %appdata% and %localappdata% \
include the user name which may include Unicode characters that after conversion \
result in the windows ‘A' methods failing to find the referenced file. I don't know \
of any work around except using Unicode filenames.

Does anyone know of a way around this.
Are there any plans of making wmanaged_mapped_file use wchar for the filenames?

Markus
