You shouldn't have a problem with using varchar and CHAR for the characters you are talking about... see the following...

Running this code...

DECLARE @i int

DECLARE @str varchar(222)

SET @i = 33 /*Start at 33 to skip SPACE and non-printable characters */

SET @str = ''

WHILE (SELECT @i) < 256

BEGIN

SET @str = @str + CHAR(@i)

SET @i = @i + 1

END

PRINT @str

Returns the following...

!"#$%&'()*+,-./0123456789:; ?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~€‚ƒ„…†‡ˆ‰Š‹ŒŽ‘’“”•–—˜™š›œžŸ ¡¢£¤¥¦§¨©ª«¬­®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþ
