Microsoft Edge corrupts Nyquist code when copied from “code” boxes in forum posts.
Leading spaces are encoded, (possibly as non-breaking space?) which creates invalid characters for the Nyquist interpreter.
Other characters may also be affected (not tested).
Firefox and Chrome:
Clicking the “Select All” link does not select all, it just scrolls to the top of the page.
Internet Explorer selects and copies the text as expected.
This appears to be a bug in phpBB that has emerged due to recent browser updates breaking a workaround for a different bug. I’m discussing a possible fix with our SysAdmin.
This part is now fixed. If anyone still finds “Select All” not working in Firefox on Linux, try reloading the page (Ctrl + R) or clear the browser cache.
The problems appears to only affect leading spaces. Non-breaking spaces are inserted when copied by Edge. Until / unless Microsoft fix it, I think all that we can do about this is to say, “if you want to copy code, don’t use Edge”.
