# How do I set the \skewchar of a math font?

In this answer, I set the `\skewchar` of a font, but I think I don't do it in the right way. The problem is that it's a math font, and those seem to get initialized only when they are used, namely when the first `\$`, `\(` etc. occurs. (Is this correct?) So for example, just putting

``````\skewchar\csname OT1/cmss/m/it/10.95\endcsname=127
``````

in the preamble doesn't work; I get

``````! Missing font identifier.
\OT1/cmss/m/it/10.95
``````

I just played around a bit and used `\check@mathfonts` to initialize the fonts before the `\skewchar` command, but this seems like cheating to me. Moreover, this only initialized the sizes `6`, `8` and `10.95`.

My feeling is that the `\skewchar` command should be invoked at initialization time. Is this the correct approach, and yes, how do I implement that?

``````\DeclareFontFamily{OML}{cmss}{\skewchar\font127 }
should work. You can also put `\skewchar\font127` into the last parameter of the `\DeclareFontShape` macro.
``````\DeclareFontShape{OML}{cmss}{m}{it}{<-> cmss8t}{\skewchar\font127}
