How can I use an apostrophe as part of a custom block's name?

I 'm writing a custom block for Dijkstra's algorithm.
I couldn't get it to work with an apostrophe in: << Dijkstra's >>.
The apostroph disappears once the edit is saved (even worse, the whole thing may collapse):

Dijkstra’s shortest distance script pic (3)
Dijkstra’s shortest distance script pic (4)

As a workaround I'm using a quotation mark << " >> instead now, but that's not very neat:

Dijkstra’s shortest distance script pic (1)

Is there a way to use an apostroph as part of a custom block's name?
Thanks in advance!

Maybe a unicode char lookalike would do the job?

i found one:

U+2019 right single quotation mark
looks like an apostrophe

@cymplecy, @coder_07: Thanks for suggesting a usable workaround!
