Hi all;
I've got an application that runs fine in terminal emulator but shows incorrect double borders when run through vmware console.

Single line borders are displayed correctly.
I've already tried and set LC_CTYPE as suggested in the FAQ.

My locale:

Any tips? It would also be acceptable to convert all double borders to single one

It looks to me like your terminal emulator isn't able to print all the required characters. For example, if you run something like this in your terminal:

package main

import (
	"fmt"
)

func main() {
	fmt.Println("\u2550")
}

You should see a double line like this:

If you don't, then the font used by the emulator may be incomplete. You could check the settings and change the font maybe, I don't know. Or like you suggested yourself, change the semigraphics characters used in the Borders variable.

Let me know if any of this helps.

I've ended up changing the semigraphics characters to always use single borders. Thanks
