Is ascii character 255 an invisible character or space?

Question

I am writing some code to print overlapping ASCII character objects and I want some to be invisible instead of the typical " " white space character. Would this solve it?

cout << char(255);

Solution 1

In the most common extended 8-bit ASCII tables 255 is the 'ÿ' symbol (Latin small letter y with diaeresis). The space character is decimal value 32. So what you are searching for is probably:

cout << char(32);

Solution 2

I guess you mean when you press Alt + 255.
And no Alt + 255 is not the same as a space.

Here is a table of the characters values.

Char	Dec	Hex	Oct
SPACE	32	20	40
Alt + 255	160	A0	240

I don't know much C++ but maybe it is

cout << char(160);

To be precise, that would be the ISO-8859-x extensions such as ISO-8859-1 (which coincides with the first 255 Unicode code points)
