I don't understand the issue... since when \v and \f are escape sequences? According to the manual (, those are just regular character sequences, backslash followed with letter.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

\v and \f are escape sequences since, well, ever. PHP due to a bug had 
simply failed to implement them before. Further more, if you are using 
heredoc or double quotes you should ALWAYS escape the \ if you want it 
to be rendered properly.
