Mac is developing an Windows Phone application and his fonts that are hard-coded in English work fine. But when other languages are added and resources are used, some capital letters randomly do not appear in the correct embedded font either in emulator or in device although they are fine in the XAML editor
Various suggestions and tests followed and Mac decided that he would read the text from the resource file and assign it to the text area directly. He did this to all the upper case letters to avoid the unpredictable behaviour. Later it turns out going into the blend and font manager all the embedded boxes were ticked including the auto fill which seemed to override all the other settings. Setting the autofill OFF fixed this issue.
This discussion was selected for featuring as such random behaviour of upper case font can be pretty difficult to work around.
