determining salt strings for tripcodes

I'm trying to write a tripcode generator in Babby's first programming language, C#. I got an array of bytes that represents a password with Japanese characters in it. I've been able to encode it. The problem I'm having is making the salt string. Am I supposed to use the second and third byte or the second and third character?

Byte array: 0x25, 0xef, 0xbd, 0xae, 0xef, 0xbd, 0xb7, 0xef, 0xbc, 0xbc, 0x5f, 0x77, 0xe6, 0x96, 0xa7
Encoded: %ｮｷ＼_w斧
Resulting tripcode: xTroLlfaCE

Bytes, most likely. Are you using S-JIS for encoding the string?

No I'm using the UTF8 encoder

Bytes obviously, also translate to Shift_JIS for 4chan compatibility.

I tried using the shift-jis encoder but it gives weird results. Using the UTF8 encoder to encode the byte array gives the correct results.

You have to decode your input and then encode to Shift_JIS, which is probably what you're doing if you're inputing it correctly.

I have the array of bytes then I'd encode to shift-jis, replace characters (& -> &, etc.) which I'd pass to crypt()? What do I encode the salt with?
