Hex decoding in Encoder potential usability issue

[GoogleCodeExporter]

In the Encoding section, toggling between Text/Hex tab recalculates the values 
as displayed in the text field.

If the decoded values contains non-ASCII characters, this can lead to confusion 
when viewing the hex dump, because it doesn't accurately reflect original 
decoded value.

Re-applying the decode will address the issue.

For example, use Base64 decode on: 
k2UTHyxx5B6WoYwF1H5qvZfuVsls2tAnlZFssL1b+J4=. Then toggle between tabs.
