Confusing differences in extended ASCII descriptions: block vs U

Sometimes we see extended ascii 219 described as a block [https://coding.tools/ascii-table]

sometimes we see it as Latin capital letter U with circumflex [https://www.ascii-code.com/]

i cant seem to find details on why this is different sometimes? any insight is appreciated. thank you so much.

Solution

  • There isn't a single encoding that "extended ASCII" refers to. It just refers generally to encodings which are extensions of ASCII.

    For example in Windows-1252 and ISO-8859-1 ("latin1") the value 219 is unicode code point 219 Û (LATIN CAPITAL LETTER U WITH CIRCUMFLEX).

    But e.g. in code page 437 the value 219 is unicode code point 0x2588 █ (FULL BLOCK).
