Ipe - vektor drawing - i cannot write æ,ø,å, - danish symbols - need help with preamble

in Ipe (The Ipe extensible drawing editor) i am not able to write å or (æø). i am aware there is a preamble settup in EDIT-> Document properties.

the problem is i set the preamble up to danish, as normal. and i testet if it works in miktex (it works) but it will not work in Ipe. the letter å is displayed as blank.

documentclass[11pt]{article}
usepackage[T1]{fontenc} %thanks's daleif
usepackage[utf8]{inputenc}
usepackage[english, danish]{babel}

if i do not setup the preamble it cannot display any latex generatet symbols. (so a subscript ends up as normal latex code. P_0 but what i need to write i dont understand.

and yep you bet i did – tried leaving out

documentclass[11pt]{article}

but did not work.

this problem is in both math and normal but i write in picture as mathmod.

can someone try to use my code and try to display æ,ø,å
can someone solve the problem – tell me what i need to write in the preamble

thanks

usepackage[danish]{babel}
usepackage{amsmath}

 text{æ,ø,å}
