character assignment

[Geethakrishna Srihari]

Please explain how assignment to character takes place:

char cf = '\101'; works fine....
what does it signify?

But char c = '\1001' ; gives compilation error.

if we assign unicode, why '\u00001' gives error even though it equals '\u0001'?

'\101' is an octal representation of a number. The largest printable character is 255 decimal, or 377 octal. What is interesting is that if you assign the decimal value of '\1001' (513) to a char, that will print '?'. Why that is, I don't know. As for the unicode values, they must be exactly 4 hex digits.

'\101' == 0101 == '\u0041' == 0x41 == 65 == 'A'
