I am url encoding a string of text to pass along to a function. However, it encodes the second space in a double-space as “%A0”. This means that when I decode the string, the “%A0” is displayed as a question mark in a black box.
I really just need to be able to remove the extra space, but I’d like to understand what is causing this and how to handle it correctly.
For example:
Something Something else
Encodes to:
Something+%A0Something+else
%A0indicates a NBSP (U+00A0).+indicates a normal space (U+0020). The NBSP displays as a replacement character (U+FFFD) because the encoding of the character does not match the encoding of the page, so its byte sequence is not valid for the page.
