Strange characters – despite everything being UTF-8

Ideal Solution The ideal solution would be to go back through your content, and replace all single/double quotes using the keyboard. However, if you’re working with massive copy/pastes, … Read more
If a hacker changed the blog_charset to UTF-7 does that make WordPress vulnerable to further attacks?
< and > are encoded as +ADw- and +AD4- in UTF-7. Now imagine the following: Someone sends +ADw-script+AD4-alert(+ACI-Hello+ACI-)+ADw-/script+AD4- as comment text. It will pass all sanitation unescaped. The database expects and treats all incoming data as UTF-8.

Byte and char conversion in Java
A character in Java is a Unicode code-unit which is treated as an unsigned number. So if you perform c = (char)b the value you get is 2^16 – 56 or 65536 – 56. Or more precisely, the byte is first converted to a signed integer with the value 0xFFFFFFC8 using sign extension in a widening conversion. This in turn is … Read more
Python decoding Unicode is not supported
Looks like google.searchGoogle(param) already returns unicode: So what you want is: As a side note, your code expects it to return a utf-8 encoded string so what was the point in decoding it (using unicode()) and encoding back (using .encode()) using the same encoding?
