I assume you are talking about fonts like the wingding fonts, and no these fonts are not supported, not even in FMP. It stop sometime in version 12 I do believe. (One of the updates) I believe it had something to do with a change that Apple made at least that was the word on the forum at that time.
There are icon-characters in most fonts that can be used in FMGo. If You are on OSX, check the fonts-utility (or similar - no english system here), You can select those characters..
No there is not any icon-fonts that can be used in GO, The supported fonts for Go is listed on page 13 in the Go development Guide. https://www.filemaker.com/support/product/docs/filemaker-go/fmgo_development.pdf and as I stated in my above post the icon-fonts such as wingdings are no longer supported in Filemaker Pro 12 and above. There is a workaround to make the fonts work in Pro see this link http://help.filemaker.com/app/answers/detail/a_id/13130/~/webdings,-wingdings-and-bookshelfsymbol7-fonts-do-not-display
You can place icons / graphics on your layouts but they would not be consider icon fonts. You would have to use a webviewer to display html on your layouts, which would make it harder to modify.
The easy way was to use the wingding type fonts and they were easy to modify just like any font, which was still not supported in Go.
Currently, I hunt down icons on the internet to use on my layouts and then use a container field with no style apply, then I use scripts to change the icon to the desired icon. I would have two or three different colors of the same icon, then put the desire colored into the container field to be displayed.
I would like to see a new feature added to support some kind of icon fonts. Here is a link to make a feature request.
there are some characters that one can use on iOS, although I don't know how to get them under Windows. On OSX, it's quite easy
there was another posting about this (similar): http://forums.filemaker.com/posts/6e208d6cce
The symbol for deleting the entries is an 'icon' - character, the bullits as well. I know, it's not a special font - but there are really usable 'graphics'-characters for iOS inside the standard fonts
Using 'profiles', fonts are installable AFAIK, although not the easy way
What I often do is type or paste a character from one of the "dingbat" fonts into a paint program that I like: Paint.net--shareware no less but works great. I then edit the image, adding color or any other changes I want before saving the image as a transparent png file.
I then insert this small image file into FileMaker before deploying the file to my iOS device.
I do not paste the image from the clipboard because a bug in FileMaker results in a trashed image when the pasted image is of windows MetalFile type (Which is what you get when you paste from a clipboard in Windows). If I were to paste the image, the icon looks fine in windows but FileMaker GO and FileMaker for Mac both show a very poor quality rendering of the image.
The example from above shows real characters, they can be used in text - one just needs to know how to create them. The character map from OSX lets one doubkeclick on a character to insert it into a text in FileMaker.
There are a lot of 'graphcis-characters' from existing fonts - not every single character from windings et all, but I have found alternatives for my needs
(sorry - I did it not make clear that those examples are not graphics but font-characters from ie Arial)
You can copy fonts and paste but then it not really a font anymore, it is a graphic. When Filemaker 12 was first release you could select an icon font and use in a field just as any font, but Filemaker / Apple changed that in one of the version 12 updates.
I got the following TEXT in my all-day-used iPad app (FM13, FMGo13):
The triangle is a character, inserted via the font-palette from OSX, 'Spesen' is pure text, the whole thing is one block of text, editable, as in the browser
