I don't know c++ but you could try the plain space character with the *, or for tabs too possible [ \t]*. See regex101.com/r/zI8vS3/2 and regex101.com/r/zI8vS3/1 — chris85

[[:blank:]]* should be what you are looking for. You can also add your own shorthands with regex_traits if you want to define \h yourself. — user657267

\h matches horizontal whitespace.
It includes tabulations and unicode spaces. It's the same as [\t\p{Zs}]

If you don't want to match all unicode spaces, you can simply use [\t ] that matches tabulations and simple spaces.
