Unsupported descriptor file encodings GBK and Big5

[SuperGod]

The vmdk file header is like:

I debug the libvmdk,and find the error is happen at line 977 in libvmdk\libvmdk_descriptor_file.c

                else if( libclocale_codepage_copy_from_string(
                          &( descriptor_file->encoding ),
                          value,
                          value_length,
                          LIBCLOCALE_CODEPAGE_FEATURE_FLAG_HAVE_WINDOWS,
                          error ) != 1 )
                {
                    libcerror_error_set(
                     error,
                     LIBCERROR_ERROR_DOMAIN_RUNTIME,
                     LIBCERROR_RUNTIME_ERROR_GET_FAILED,
                     "%s: unable to determine codepage value from string.",
                     function );

                    goto on_error;
                }

so maybe libclocale_codepage_copy_from_string not support code page string like "GBK"?

That could be correct, this part of VMDK was undocumented last time I checked. I'll have a look to add GBK support when time permits.

I have got the save problem,and the vmdk coding is 'GBK' and 'Big5'

[joachimmetz]

GBK support which is presumed to map to Windows cp936 for now added in a3f6142

[joachimmetz]

"Big5" also seems to be a broader standard like GBK but I'll map this to windows cp950 for now

Big5 support which is presumed to map to Windows cp950 for now added in 4b09bb8

based on libyal/libclocale#5, one thing that could be useful is to create a VMDK with an "euro sign" that can be shared. That should give more resolution on which encoding is actually used for GBK.
