#1391 Gnuplot-wxt Error on Cygwin

[Anonymous]

I have buit cvs version of gnuplot with wxt terminal on Cygwin (32 and 64 bit)
The wxGTK-2.8.12 is used.

gnuplot> plot sin(x)

The plot is successful but an error dialog appears and says:

Gnuplot-wxt Error
Cannot convert from the charset 'Unknown encoding (-1)'!

The dialog is attached.

I searched the keyword of "Gnuplot-wxt Error" and "Cannot convert from the charset"
in the cvs sources using grep like feature the editor I am using.
But I cannot find them in the cvs source.
So I could not have no clue to access the issue.

Any suggestions?

I executed gnuplot on wmaker on Cygwin/X. This time "Gnuplot-wxt Error" did not occur.
I cannot find out the reason why.

I executed gnuplot (cvs 2014-04-27 Ethan A Merritt ) on Cygwin_x84-64 using GNOME-openbox.
"Gnuplot-wxt Error"

Sorry the previous post is incomplete.
The error

Gnuplot-wxt Error
Cannot convert from the charset 'Unknown encoding (-1)'!

was appeared on GNOME-openbox (Cygwin-64).

If we set LC_ALL, the error message disappeared.
Sorry for the noise and please close this ticket
