How can I create Arrow type of Bullet points in Adobe Frame Maker?

See also the suggestion ⎆in your duplicate thread.

If your main document font populates the codepoint for a suitable Unicode arrow or arrow-like glyph, use that, as described on the other thread.

If your font doesn't, and you have to resort to another Unicode font, use a Character Format that just calls for Font Family.

Avoid using a legacy codepage font such as Wingdings, as the intended glyph will not survive into all output workflows.

Wingdings [→] (0xE0) may be expected to render as [à] in HTML/XML output.
U+2192 (\u2192) RIGHTWARDS ARROW would be what you want for that arrow.

Wingdings 3 is mostly arrows. Create a character style and apply it in the numbering section of the paragraph style. 

Here is a link to a PDF that shows the various wingding and webding characters:

Here's a breakdown of using characters in free custom fonts for bullets and setting size/color.

I also use a MIF fragment (p485 of FrameMaker - Working with Content) to adjust the baseline shift for the large icons I use for Warnings, Notes, and Cautions.

Baseline Shift isn't explicitly available in the Character Designer, so I set the FDY property via MIF as in the following example:

<FontCatalog
<Font
<FTag `FontAwesome'>
<FFamily `FontAwesome'>
<FEncoding `FrameRoman'>
<FSize 28.0 pt>
<FDY 45.0%>
<FLocked No>
<FSeparation 5>
<FColor `2017 Accent Color'>
> # end of Font

> # end of FontCatalog

# End of MIFFile
