I'm retrieving the messages of my Gmail account, and I'm finding '=' signs in the body, with some hex codes.
This is an example:
Na pagina= para anunciar poderia ter as op=C3=A7=C3=B5es de Estados , Cidades e Bair= ros .
Ex : S=C3=A3o paulo
Diadema , Sant=
I have highlighted in bold these parts. Of course, in Gmail these codes are not visible.
What should I do?
They're in quoted-printable encoding.
You can use PHP's built-in quoted_printable_decode() function to decode it.
These look like escape codes, the type that, if they were in a URL, would normally be %C3%A7%C3%B5. This has them in decimal. Are the characters showing up at all, as in, do they take up any space in the string? I think they are special characters with diacriticals...
S=C3=A3o paulo, in particular, seems to agree with this assessment.
