将希腊HTML字母抄录到LaTex时出现问题

Question

I have the following HTML string:

s = "I have : <i><λv<sub>1</sub>,w> + <v<sub>2</sub>,w></i>"

Now, I would like to convert it to LaTex. To do so, I am using pypandoc .

import pypandoc
text = pypandoc.convert_text(s,'latex', format = "html", extra_args = ['--wrap=preserve'] )
text

I get:

I have : \emph{1,w\textgreater{} + 2,w\textgreater{}}\r\n

which in readable LaTex becomes:

Anyone knows how to fix it ?

Funny enough, if I just type the above string into Stackoverflow, I get the correct output:

I have : <λv ₁ ,w> + 2,w>

I am interested in a general solution, not a manual fix for this particular example, since I have massive amounts of html text that I need to transcribe.

How can I achieve this for LaTex ?

Answer 1

Doing some Quantum homework? Try using the symbol escapes built into LaTeX. For example, \\lambda.

I have : \langle \lambda v\sub{1}, w \rangle + \langle 2, w \rangle
