How can you use the two symbols in the Math mode?
My tex
$\matbb{Z}$
$\textregistered$
My formatting code
\documentclass{bmcart}
%%% Load packages
%\usepackage{amsthm,amsmath}
%\RequirePackage{natbib}
%\RequirePackage{hyperref}
\usepackage[utf8]{inputenc} %unicode support
%\usepackage[applemac]{inputenc} %applemac support if unicode package fails
%\usepackage[latin1]{inputenc} %UNIX support if unicode package fails
\usepackage{amsmath, amsfonts, amssymb}
\usepackage[T4, OT1]{fontenc}
\usepackage{newunicodechar}
%\usepackage{unicode-math}
\newunicodechar{ƒ}{{\fontencoding{T4}\selectfont\m f}}
\newunicodechar{Ƒ}{{\fontencoding{T4}\selectfont\m F}}
I get these warnings and errors

Use
mathbb
instead ofmatbb
and try$\text{\textregistered}$
instead of$\textregistered$
.Also, be aware that the basic
LaTeX
\textregistered
command produces a "faked" symbol. To get a better-looking symbol, be sure to load thetextcomp
package.
