Public bug reported:
I'm writing C applications for Ubuntu and I've find out interesting bug.
That's a short program showing what's wrong. It reads a line from user
and writes that line.
"#include <stdio.h>
void main()
{
char buffer[1024];
for (;;) {
fgets(buffer, sizeof buffer-1, stdin);
printf("%s\n", buffer);
}
}"
When I'm using a gnome-terminal with UTF-8 encoding, if I write in this
program a string "Hello!", then delete it all with Backspace, than press
Enter, I'll see: program have red an empty string, as expected. Then I
write "123", delete it, press Enter and see: program have red an empty
string, as expected.
But if I write a string on russian, for example "Привет!", delete it all
and press Enter, i'll see that program had red a string "Пр". If after
full deletion of "Привет!" I write a string "123", it will show
"При123". And this problem is happening with any Unicode russian string,
that need to be edited, even if you want to replace only one symbol:
say, I'm enter "Привед", delete one character and press "т" to change it
to "Привет" - than program says it red a string "Приве�т". There's no
such problems if I enter strings which contain only english letters
and/or numbers.
There's no such problem if I use any other encoding, which can be
selected in gnome-terminal menu: KOI8R, WINDOWS1251, ISO-8859-5. I
didn't noticed such problem on both XTerm an UXTerm, probably because
they're don't using Unicode; there's also no such problem on LXTerminal,
XTerm and UXTerm on my other machine running Lubuntu, probably by the
same reason.
Thanks you very much in advance for any efforts to solve this issue.
