>From The Unicode® Standard Version 12.0 – Core Specification: "5.7 Compression ... Encoding forms defined in Section 2.5, Encoding Forms, have different storage characteris- tics. For example, as long as text contains only characters from the Basic Latin (ASCII) block, it occupies the same amount of space whether it is encoded with the UTF-8 or ASCII codes. Conversely, text consisting of CJK ideographs encoded with UTF-8 will require more space than equivalent text encoded with UTF-16."
