As recent as REALbasic 4.5 LR they were referred to as:

"Table 6 presents the high ASCII character sets for the Mac and  
Windows platforms"

and identified as "Table 6: Extended ASCII Codes (Macintosh and  
Windows).".

Of course, they only exist "as is" in the MacRoman or Latin1  
character sets. That also was before Rb used UTF-8 encoding that  
began in Rb 5.0.

So, "High ASCII" should work correctly in those encoding formats as  
well.

PS. At one time, chr(128) to chr(255) were used for a very primitive  
set of "Graphics" and many games used them for that purpose but I am  
really dating myself now. :)
