Lỗi some characters cannot be mapped using cp1252 character encoding năm 2024

First, this is minor because the workaround is simply to switch to UTF-8 instead of CP1252. But CP1252 is the default for an Eclipse project on Windows.

To reproduce :

• Set your Ceylon project encoding to CP1252
• Then create this class

class Location(unLocode, String simpleName) {

shared String unLocode;
shared String name => simpleName + " (" + unLocode + ")";

And try to inline rename (Shift+Alt+R) the class parameter simpleName to simpleName2

You get

!MESSAGE Some characters cannot be mapped using "Cp1252" character encoding.
Either change the encoding or remove the characters which are not supported by the "Cp1252" character encoding.
