You could try inputting your name as [Latin Small Letter E][Combining Acute Accent]:

e◌́ => é

Which should keep the `e` intact, while the combining acute accent (0xCC 0x81) may "only" get converted to a `Ì` which may be stripped. 0x81 is undefined in Windows-1252, so I have no idea what would happen to that, but probably be stripped as well, keeping just Leon.

Unless someone decides to NFC-normalize the text along the way. And it's generally agreed that text should be normalized with NFC, although there is often a fierce debate about who should do it ("not me").
