To whom this may concern,
I want to insert a blackboard bold 1 in lyx (For the identity matrix)
(Unicode: 𝟙), but I can't seem to find anyway to do it. I tried
changing the encoding to the various unicode types in the document
settings (Document->Settings->Language-Encoding-Other), but all of the
encoding types produce errors. In LaTeX, typically dsfont is used, but
\(\mathds{1}\) produces no result (within lyx).
But it does work on the output, right? At least, once you add
\usepackage{dsfont} to the preamble. Worked for me.
I could import the package in the preamble
(Document>Settings>Preamble) via \usepackage{dsfont} (untested), but I
would like to avoid the Evil Red Text.
I have never run into this, but I also never tried it. You could use
\mathbb{I} instead -- but the blackboard bolds within math mode, as far
as I know, only apply to capital Roman letters (I use R, C, H, and Z all
the time).
