Problem with tildes in Harlowe Twine 2

Twine 2 & Harlowe.

I want to be able to put punctuation inside macros.

According to the "Verbatim markup" section of the Harlowe manual, if I want to use punctuation within a macro call, I should use tildes (or graves, it's not clear--the text says tildes but the actual mark they use is a grave). However, when I try this, it doesn't work. The output is always "unexpected markup". Can anyone tell me what I'm doing wrong? I've tried so far:

(print: "He said, "Hi." ")
(print: "He said, `"Hi."`")
(print: "He said, ~"Hi."~")
(print: "He said, ``"Hi."``")
(print: "He said, ~~"Hi."~~")

In another example, I can't seem to get question marks to work inside click-append, like so:

Do you want to make a wish? (click-append: "Do you want to make a wish?")[Ask and ye shall receive.]

With this example, the clickable link doesn't appear in the playthrough.

Is this just a known issue and I'll have to work around it? Thanks!
