The reason this happens:

In notepad, any other 4-3-3-5 letter word combo will have the same results.
It is all to do with a limitation in Windows. Text files containing Unicode UTF-16-encoded Unicode are supposed to start with a "Byte-Order Mark" (BOM), which is a two-byte flag that tells a reader how the following UTF-16 data is encoded.

1) You are saving to 8-bit Extended ASCII (Look at the Save As / Encoding format)
2) You are reading from 16-bit UNICODE (You guessed it, look at the Save As / Encoding format) This is why the 18 8-bit characters are being displayed as 9 (obviously not supported by your codepage) 16-bit UNICODE characters
