Unicode icon codes not searchable

[nueverest]

If I go here https://design.google.com/icons/, and type  into the search bar I get zero results.

Adding unicode icon representations to the search index would help since I need to support old versions of Android that do not support ligatures, and I do not remember what all of the unicode values mean.

Also explicit ligatures like mode_comment are not searchable. I have to type mode comment without the underscore.

It is now https://fonts.google.com/icons but the limitation is still there with the new site.
