When the Characters %(zero)a - %(zero)f are used in a string, these values disappear when retrieved from the database

Strings or file names containing %(zero) in Additional Comments or Work Note get displayed by the interface removing these characters.
This information was correctly getting saved in the database, but when called back to display that value, this characters would vanish leaving nothing there.
The characters actually show if for example starting with %0g .
This may be due to encoding, so far reproduced on Dublin, Eureka, and Fuji (HI).
