@GLORIA VINCIT
hmm...what does color triangles mean?... I don't get what is your problem.
anyway, if you made text field on Procedural-Object, you can choose font. there are two fonts "erSymbols1" and "erRoadSymbol1"
if you click font name, characters table window will be popped up and you can find character what you needed.

if you need more help about PO-Text Customization, read this link.😇 http://proceduralobjects.shoutwiki.com/wiki/Text_Customization

I don't see any of the color triangles shown in your screenshot.

정말 최고입니다 선생님
