Unfortunately my knowledge about "EUC-JP" and "Shift_JIS" is best expressed by 
"nil", so I don't know if there is something like a "BOM" for data 
identification. For Ascii, extended-Ascii (eight valid bits, e.g ISO-8859-1), 
and UTF-8 I understand, that the following is true for Ruby 1.9(.0) in the 
moment and will be true for Ruby 1.9.x (x>=1):

1 - If a "magic coding comment" is found inside the Ruby source (produced by an 
editor or inserted manually), the source will be expected written in the given 
encoding (this means, that the "magic coding comment" must have same bit pattern 
in all possible encodings).

2 - If there is no "magic coding comment" found in the source, but the file 
begins with an UTF-8 BOM (0xEF, 0xBB, 0xBF), the source will be processed as 
UTF-8, and the BOM will be ignored.

3 - If there is neither a "magic coding comment" nor an UTF-8 BOM in the source, 
it will be expected as ASCII, where characters not in range (0x00..0x7F) are 
invalid outside String constants and comments.

Five questions:

- Is this the correct sequence ("magic coding comment" before looking for an 
UTF-8 BOM)?

- Are there "magic byte sequences" for "EUC-JP" and "Shift_JIS"?

- Does a complete list of possible "magic coding comment"s exist? - Where?

- Are there wrong parts inside my description?

- Will this behaviour stay stable in Ruby 1.9.x (x>=1)?

I would like to put this information as soon as possible together for 
documentation purposes.

Wolfgang N疆asi-Donner
