Same answer as two posts down:
Though from what I see this character is within the primary Latin encoding range and should show up without issues even if your system is configured to a different default language. On my system I can use it just fine (Windsows Vista, German) when I copy&paste it from the charmap utility and use a font that has all Unicode characters (Arial, Times etc.) so if it doesn't show up, this may depend on the specific font used and how it maps the glyphs to different ranges or your system language...
hmm that umlaut not works only with AE. Other softwares shows it without problem. I have change Unicode settings of my windows but still same
i am going to see the other thread which is linked above.
Nope not worked i have played with regional language settings, it is completally not affects AE.
Is there are another solution please ?
