What 𝚑 means
In Word, type 1D691, then press Alt+X.
If other hexadecimal digits come right before it, select only 1D691 first; otherwise Word may convert the wrong string.
Before this character was encoded, scientific publishers already used mathematical letter styles to distinguish symbols. The 1998 Unicode proposal says these differences could be critical to meaning and aimed to carry them in plain text.
What does the monospace h mean in math?
It is a lowercase h whose style can mark a distinct symbol.
This monospace h belongs to a mathematical alphabet; each letter occupies the same width, like in typewriter text. In a formula, its style can distinguish one symbol from plain h, while the formula supplies the value or role.
Why can 𝚑 look different across fonts?
The style is fixed; its exact drawing is not.
Unicode identifies the monospace mathematical style, not one typeface; different fonts can draw it differently.

Questions people ask
1Can NFKC turn 𝚑 into plain h?
Yes. NFKC is a compatibility-normalization rule that folds this mathematical form to plain h, dropping the style. NFC does not fold away that compatibility distinction.
