[Seaside] Downloads and filenames with diacritics

[Boris Popov, DeepCove Labs]

To ensure you preserve characters, you need to go via the proper utf8 encoder when going from characters to bytes and vice versa.

Yeah, that is sexy.

It also needs it's complement:

String class>>fromHex: anHexString
"It returns the string that has its characters encoded in hex.
'el ñandú' asHex 
String fromHex: '656C20F1616E64FA'.
Play with those."

^ String streamContents: [:stream| |source|
source := anHexString readStream.
[source atEnd] whileFalse: [
stream nextPut: (Character value: (Integer readFrom: (source next: 2) radix: 16))]].

	Yeah, we actually saw that possibility but I was hoping to make the app not to be forced to maintain the original name in the database (so it can't never be confused about it nor inject maintenance costs).
	
	What do you guys think about some other way to encode the filename that preserves the original (with diacritics) but for the OS (and xsendfile) it can look like a non-diacritical one?
	
	any ideas? (or encoders to suggest?)
