To reproduce

echo "I would like a (big) steack, in a [large] hamburger {yes}!" | phonemize -l en-gb --preserve-punctuation

aɪ wʊd laɪk ɐ bɪɡ stiːk, ɪn ɐ lɑːdʒ hambɜːɡə jɛs!

Expected behavior
parentheses, brackets, braces, and other kinds of punctuations should be provided in the output.

@mmmaat & @jncasey do you think that we should add these punctuation ((){}) marks to the _DEFAULT_MARKS constant?

[jncasey]

Before the feature to define punctuation with regex, I was typically using ;:,.!?¡¿—…"“”-()‘’*[], so It'd make sense to me to add (){}[] to the defaults.

Sure I agree, why not!
