Customize CancelDlgIcon to show Warning symbol

Question

I need to show warning image instead of information image for CancelDlg in wix. I was able to do that by adding the following code:

<String Id="CancelDlgIcon" Overridable="yes" Localizable="yes">WixUI_Ico_Exclam<String>

However I have builds for different languages for e.g. fr-fr, ja-jp, en-us, etc.

Only for en-us it is working fine. For other languages the warning icon is not displayed :(

Can anyone please help me and let me know what changes to make so that it works for all languages (es-es, en-us, fr-fr, ja-jp etc)?
