What do machine dependent characters mean?

Machine dependent characters are new restrictions on new SKU migrated Rakuten stores. Rakuten will no longer accept characters such as Roman numerals in raw format (as is). Therefore, we have to process these characters differently than the rest of the texts, which eventually causes an increase in texts' overall lengths. In general, one machine dependent characters could take up the size of 8 characters combined.
