Notepad++ doesn't come into play, here. You send a message from Dialog
Editor. And depending on the characters found (in the current message),
Dialog checks its encoding settings and formats the text to 7-Bit-ASCII,
Windows-1250 or its siblings, CP850 or its siblings, UTF-7, UTF-8,...
Every message /may/ be sent with a different encoding.

The OnBeforeSending script needs to replace characters formatted in one
of the afore mentioned encodings. The letter ä, for instance may be
found in this text buffer as char 0x84, 0xE4, word 0xC3A4 and in several
other ways. Each variant has to be replaced, if the source encoding is
not fixed. (Which in itself usually wouldn't be a good idea, either.)

Moreover, replacing a character 0x84 with (e.g.) ae under the assumption,
it would have the meaning ä, could be wrong, altogether. If the source
encoding happens to be Ansi-1252, this byte position represents the lower 
curly quotation marks.
