Checked with the latest development build

• [X] I made a backup of my libraries before testing the latest development version.
• [X] I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Define a "Customized entry preview" like this: "\format[Replace("é,e")]{\author}"
2. Test it with an entry having "Testé" as author. The preview show "Teste" as expected. The accent is replaced with the non accented character
3. Create a new "Custom export formats" with the same formating saved in the .layout file: "\format[Replace("é,e")]{\author}"
4. Export the entry having "Testé" as author. The resulting exported file contains "Testé" as if nothing had happend. I guess accent are converted to some encoding BEFORE being processed by the formating and the replace function can't find them anymore.
