Ligatures like \ae are specific to the LaTeX (and thus PDF) writer, so they don't work in any other formats. Pandoc just passes it through unchanged. For HTML output, you can use an entity: `Æ` or `æ`, for upper case or lower case. Another option is to use the unicode character directly (how you do this depends on your system and text editor; in Windows hold Alt and type 0230 on the number pad; in vim type CTRL-K a e; use a character-map app, etc.) This should work for most output formats. It'll work with LaTeX if you use XeLaTeX or LuaLaTeX, as those allow unicode input.

I want to publish a document with an \ae ligature to html and to pdf. The latex form "\ae robic" converts to the appropriate form and displays properly in pdf, but the html just drops the ligature.

Simple test case:

chriswri$ cat > test.txt

\ae robic

chriswri$ more test.txt

\ae robic

chriswri$ pandoc -t native test.txt

[Para [RawInline (Format "tex") "\\ae ",Str "robic"]]

chriswri$ pandoc -t html test.txt

<p>robic</p>

What's the best way around this - write a filter? finding some docs that will help? (I've found that ... is automatically converted to an ellipsis  - so \dots isn't necessary).

with thanks
