Yes, I can confirm: it works! It works also in my own test files –  
except one: the ISO 8859-6 encoded one. I was searching for HYPHEN- 
MINUS, U+00AD. I'll attach my test file. It could be also useful in  
the ISO 8859-6 possible bug I reported recently.

I did not try this test because it is too simple: LATIN SMALL LETTER  
A WITH ACUTE (U+00E1) is in the two encodings on 341/225/E1.

Please use my answer to Miles Bader as test case! I can send you my  
other ISO 8859-X test files.
