In Europe, we use the Euro. On our keyboard this is represented next to the 5. I type the Euro symbol (€) by typing Alt Gr -5 (ALT Gr is the Alt key on the right of the space bar).
In Confluence, ALT GR-5, immediately equates to H5, rather than the € symbol. In all applications I know except Confluence, ALT GR-5 is always interpreted as Euro symbol rather than ALT-5.
Is it possible to configure Confluence so that ALT GR-5 becomes the € symbol rather than the Header 5?
