When open a file containing a Unicode character that cannot be converted into the specified encoding, a warning message will be displayed: "Some characters cannot be converted using the specified encoding. The file will be corrupted if you continue editing and save the file." For instance, if you try to open a Japanese EUC file with the Japanese Shift-JIS encoding, and if the file contains a character code value not in the range of the Japanese Shift JIS encoding, the warning message will be displayed.
Even if this check box is checked, some encodings will not display the warning message. For instance, trying to open a Japanese Shift-JIS file with the Japanese EUC encoding will not display the warning message.
