You would need to use Unicode functions to get symbols like that to display; its possible there aren't any in..win32lib.ew?, its been a long while since I've used Windows.. The documentation should say, but its not available online.
I get the same problem with down arrow (ascii 281) and up arrow (ascii 280).
Where are you getting these codes, btw? ASCII (actually, I think Windows uses Windows-1252) is 32-255 (with a few left out in the middle).
I'm getting from this test program that I wrote:
include get.e integer c,i c=0 procedure print_out(integer c) for x=1 to 20 do puts(1, sprintf("x=%2d",x) &" ") puts(1, sprintf("c=%2d",c) &" ") puts(1, sprintf("c+x=%2d",x+c) &"=") puts(1, sprintf("%s",x+c) &" ") puts(1, sprintf("%2d",x+c+20) &"=") puts(1, sprintf("%s",x+c+20) &" ") puts(1, sprintf("%2d",x+c+40) &"=") puts(1, sprintf("%s",x+c+40) &" ") puts(1, sprintf("%2d",x+c+60) &"=") puts(1, sprintf("%s",x+c+60) &" ") puts(1, sprintf("%2d",x+c+80) &"=") puts(1, sprintf("%s",x+c+80) &" ") puts(1, sprintf("%2d",x+c+100) &"=") puts(1, sprintf("%s",x+c+100) &" ") puts(1, sprintf("%2d",x+c+120) &"=") puts(1, sprintf("%s",x+c+120) &" ") puts(1, sprintf("%2d",x+c+140) &"=") puts(1, sprintf("%s",x+c+140) &"\n") end for end procedure while 1 do print_out(c) puts(1, "hit any key\n") i=wait_key() c+=20 end while

DOS (including command prompt, which emulates it) is completely different than Windows; DOS defines the control chars (1-31) and extended ASCII (128-255) to be block drawing elements and some other things. Anything above 255 most likely just wraps back around, since DOS and legacy Windows only supports character sets of at most 255 symbols (one byte) at a time. Unicode supports many, many more (including arrows, snowmen, hotels, monochrome blue hearts, etc), but my current understanding is that Eu has very limited support for it..
