Convert from one power-of-2 number base to another.
If padding is enabled, this always return true. If not, then it returns true of all the bits of the input are encoded in the output.

Tests if the given character is a whitespace character.
The whitespace characters are: space, form-feed (''), newline ('
'), carriage return (''), horizontal tab (''), and vertical tab ('').
This function is locale independent. Under the C locale this function gives the same result as std::isspace.
