Converting Hex to ASCII

[keithglong]

Hi All,

I am trying to convert Hex to ASCII, similar to the Hex to ASCII Text Converter at:

http://www.rapidtables.com/convert/numb ... -ascii.htm

When I enter 57612be9 and click on the "Convert" button, I get the following value:

Wa+é

Using the binaryEncode function in LiveCode...

Code: Select all

answer binaryEncode("H*", "57612be9")

I get Wa+È

Any idea as to why that last character is off? Any feedback would be most welcome.

Thanks!

Sincerely,

Hi Keith

The last 2 hex digits correspond to the 233rd character of the Extended ASCII Character set, which may vary on different platforms and computers for several reasons. The web calculator most likely uses a different Extended ASCII Character set from that used by LiveCode on your computer.

However, you can be fairly confident that the actual *binary* value would be the same across all platforms. The difference comes in when the binary value is converted to text.

Here's a Wikipedia article explaining how such differences can be commonplace:

Kind regards,

Hi Boo,

ASCII 233 for Win/ISO is é
ASCII 233 for Mac is È

Apparently you are using a Mac and LC returns the Mac ASCII value

if you force LC to interpret ASCII 233 as ISO by using isoToMac it will translate to é

Code: Select all

answer isoToMac(binaryEncode("H*", "57612be9"))

a bit confusing.

I looked here:

Correct.
