How to fix CONSTANTS for custom fields?

Hi,
So I have created some custom fields, and the label was created in my language, and the language have this characters: Ț Ș Ă Î Â .
I have this custom field: Colecție and the constant for this is COLEC__IE .
The constant is generated automatically from label every time is displayed?
Because I can't find the constant in any language file or in database.

For now I will use COLEC__IE to translate the content.

Thank you, and LLHS!

I'm an idiot... I should have realized that I should write the label without diacritics and overwrite the translation, I apologize nicolas.
Thank you!
