Using bm with eulervm gives inconsistent ‘’ characters












7














I prefer to use bm package to bold math. However, I noticed that when used with eulervm, this gives inconsistent results for ‘<’ and ‘>’ characters.



I wonder what causes it and can the usage bm be fixed to get proper ‘<’.



documentclass{article}

usepackage[utf8]{inputenc}
usepackage[T1]{fontenc}

%usepackage{amsmath}

usepackage[euler-digits,euler-hat-accent]{eulervm}

usepackage{bm}

begin{document}

texttt{hphantom{mathbold}llap{bm}}: quad $ 1 + 1 < 3; quad bm{1 + 1 < 3} $

texttt{mathbold}: quad $ 1 + 1 < 3; quad mathbold{1 + 1 < 3} $

end{document}


MWE

There is an inconsistency in the shape of < and > in the zeurm10 and zeurb10 fonts used for the symbols with eulervm active:



documentclass{article}

usepackage{amsmath}
usepackage[euler-digits,euler-hat-accent]{eulervm}
usepackage{bm}

begin{document}

begin{tabular}{@{}ll@{}}
bm: & $1 + 1 < 3$; $bm{1 + 1 < 3}$ \
mathbold: & $1 + 1 < 3$; $mathbold{1 + 1 < 3}$
end{tabular}

{usefont{U}{zeur}{m}{n}symbol{"3C}}

{usefont{U}{zeur}{b}{n}symbol{"3C}}

end{document}


enter image description here



With mathbold, which is a math alphabet selection, only letters and numbers become bold, but not other symbols.



You can work around the inconsistency by using Computer Modern for the < and > symbols.



documentclass{article}

usepackage{amsmath}
usepackage[euler-digits,euler-hat-accent]{eulervm}
usepackage{bm}

DeclareSymbolFont{cmletters}{OML}{cmm}{m}{it}
SetSymbolFont{cmletters}{bold}{OML}{cmm}{b}{it}
DeclareMathSymbol{<}{mathrel}{cmletters}{"3C}
DeclareMathSymbol{>}{mathrel}{cmletters}{"3E}

begin{document}

begin{tabular}{@{}ll@{}}
bm: & $1 + 1 < 3$; $bm{1 + 1 < 3}$ \
mathbold: & $1 + 1 < 3$; $mathbold{1 + 1 < 3}$
end{tabular}

end{document}

    @barbarabeeton Of course they aren't the same: mathbold is a math alphabet switch, which doesn't act on symbols such as <.

mathbold is math alphabet command (like mathbf, mathit etc) so it has no effect on < . bm though does affect < and you get the character that the package sets up for boldmath, If you add



boldmath

$ 1 + 1 < 3showlists$


You will see that bm is selecting (in normal math) the fonts used in boldname.



In this case that is



....U/zeur/b/n/10 <


But as you show the bold font's < is a rather different shape to the medium weight font



So this appears to be a font issue.

    But as you show the bold font's < is a rather different shape to the medium weight font



    So this appears to be a font issue.
