Hi,


Hello,

Just to clarify on the Windows terminal issue: The Karaf console works
fine; it's only the rendering of tables that is using a weird character
instead of the standard pipe (|).

I suspect this is an issue within JLine.


Indeed that seems to be the case:

https://github.com/jline/jline3/issues/1366

reported against Karaf and jline-3.22.0.

The characters used here are:

ASCII code 191 = ┐ ( Box drawing character single line upper right corner )
ASCII code 192 = └ ( Box drawing character single line lower left corner )
ASCII code 193 = ┴ ( Box drawing character single line horizontal and up )
ASCII code 194 = ┬ ( Box drawing character single line horizontal down )
ASCII code 195 = ├ ( Box drawing character single line vertical and right )
ASCII code 196 = ─ ( Box drawing character single horizontal line )
ASCII code 197 = ┼ ( Box drawing character single line horizontal vertical )

These are all have the top bits set, so are encoded as multi-byte sequence in UTF-8 -- in this case 3 bytes, which explains the three weird characters (which depend on local code page, I guess).

Without knowing anything about JLine, I suspect this is caused by https://github.com/jline/jline3/commit/d6e84da4b7a55985fbf8b83b155da3811b0631d8

It drops the codepage argument from terminal/src/main/java/org/jline/terminal/impl/AbstractWindowsTerminal.java and moves it to terminal/src/main/java/org/jline/terminal/TerminalBuilder.java

I think we are ending up with UTF8 instead of the default charset... I am not sure if Karaf can do something about that or it's something that needs fixing in JLine.


Regards,
Robert

I have to test a potential issue about the terminal with Windows

platform,

but definitely not a blocker for this release.
