The table is assumed to have at least two fields with the `name` fields set to `key` and `value`. Both values are expected to be strings. The key string is parsed as a hexadecimal numeric literal (e.g. `0x1234`) and converted into a number.  The table returned will then have numbers as the keys and strings as the values.]==] function export.dataset(dataset_name) local dataset = mw.ext.data.get(dataset_name)  if not dataset then return nil end  -- Check schema. local charcode_index = nil local value_index = nil for index, field in ipairs(dataset.schema.fields) do local field_name_lower = field.name:lower() if field_name_lower:find("key") then charcode_index = index elseif field_name_lower:find("value") then value_index = index end end  if not charcode_index then error("Character code field not found in data schema.") end if not value_index then error("Character code field not found in data schema.") end  -- Extract values from dataset data. local result = {} for _, item in ipairs(dataset.data) do result[tonumber(item[charcode_index])] = item[value_index] end  return result end  return export
