chars not show in PS CS2, but in test mode ok

Hi,

I would like to complete a font with 4 hungarian chars
$150 latin capital letter O with double acute
$151 latin small letter o with double acute
$170 latin capital letter U with double acute
$171 latin small letter u with double acute
So I added this chars in insert characters menu, and added the glyphs o, O, u, U and the ‘double acute acent’ [mapped $02dd], which was originally in the font.
When I test the font, the four chars work as I want.
In word, when I the new chars first, it changed times new roman. I delete back, and type some old chars, and again, from that it works correctly.
But in Photoshop CS2, the new characters don’t appear, instead it fall back to times new roman.

Any advice is appreciated

thank you

Try Format, Settings, Ranges, Unicode Character Ranges, Calculate,
and Code Pages, Calculate.

Then uninstall the old font and reinstall the updated font.

Thank you very much.
It seems it works now!
