Wrapping specified text in cell with <strong>#</strong> for Anki

I am unsure how I might accomplish this but suspect there may be a formula.

In column A, I have the word I am learning in Anki. In column B, I have the text I would like to wrap (e.g., <strong>B1</strong>). And in column C, I have my desired output. Below is an example of what I would like to achieve. The solution must be able to recognise non-English text, e.g., ?, ?, and ?.

Example:

Column A

sine
?vrig
bog

Column B

i
?v
g

Column C

s<strong>i</strong>ne
<strong>?v</strong>rig
bo<strong>g</strong>

Any help is appreciated.

EDIT: as you can see, this forum doesn't recognise Danish characters! The characters I am referring to are the three extra letters in the Danish alphabet.
