Lot’s of characters doesn’t show up in my system. Instead I see some question boxes. I’ve tried to fix this installing tons of font package but that didn’t work. Recently when I ran a C program to show the output of Extended ASCII Character it showed only question boxes.
Now what should I do to make it show those characters?
Trying to print a character in the range 128…255 will output a byte with the given value, but how that byte is displayed is determined by your terminal and how it is configured. Most likely, your terminal expects all program output to be UTF-8 encoded; For backward compatibility with ASCII, all bytes less than 128 are valid characters in UTF-8, but when bytes 128 and above are involved, only certain sequences are valid and a single byte with its bitset high is an error .
Check your locale
