.Net Reflector Red and green squares

What are the green a开发者_JAVA技巧nd red squares? Are these variable names and strings being obfuscated purposely? Is there a 'deobfuscator'?

At a glance I would say it's unicode characters which don't have a printable representation

What you are seeing is probably the result of an obfuscator. The characters are appearing as boxes because the font you are using in Reflector does not have a glyph for the character being shown.

I think Dotfuscator does this type of obfuscation. You can check by looking at the attributes of the assembly for a Dotfuscator attribute.
