How Ultra Double-Struck is produced
This style is a direct character map. Every letter you type is looked up in a table and replaced with a different Unicode character that resembles a styled version of it. Nothing is computed and nothing is added โ it is a one-for-one substitution, which is why the output length matches your input almost exactly.
Because the letters are genuinely different characters, the result is not searchable, screen readers may announce it a character at a time, and any field validating its input against ordinary letters will reject it. It will, however, survive being pasted anywhere that accepts plain text.

Where it works
About this family
These come from the Mathematical Alphanumeric Symbols block, added to Unicode so a formula could distinguish a bold vector from an ordinary variable. That origin is why the coverage is unusually complete: mathematicians needed the full alphabet in both cases plus digits, so you get all of it.
Before you use it
Because these are separate characters rather than a font weight, a screen reader may announce them one letter at a time. Use bold for a name or a heading, not for a whole paragraph.
