Background knowledge

Unicode

Unicode assigns common numbers to characters. A code point is such a number: A is U+0041. Character identifiers, visible glyphs and stored byte representations are different concepts.

bytes

ASCII characters count as 1 byte; non-ASCII characters count as 2 bytes per Unicode code point. This is not an actual encoded size or file size.

Notes

• ASCII characters count as 1 byte; non-ASCII characters count as 2 bytes per Unicode code point. This is not an actual encoded size or file size.
• Characters are Unicode code points; combined emoji can count as multiple characters.
• Excluding whitespace removes spaces, tabs, line breaks and other whitespace characters.
