There are uncountably many infinite strings, if you permit any content whatsoever. But when you have some restrictions, that may be, or may not be the case.
Take for example rational numbers a/b, where 0<=a<b and a and b are naturals. They represent countably infinite number of infinite sequences.

These restrictions here may do the same.
