When viewing a manual (man gcc for exampe), the quotes areound `quoted' text is being displayed a 3 character sequence.

For example, the word Don't appears as Don<a^><euro><tm>t (where each <.> is 1 symbol).

The same happens in error messages generated by gcc.

How to I alter this character mapping behaviour?

**EDIT** Could a moderator move this to the Fedora forum for me thanks

What terminal are you using ?

It sounds like a character encoding problem. In gnome-terminal just go settings->character encoding

In konsole settings->encoding

Its a plain telnet session (telnet-server), no X involved.

It does it when using windows telnet client, cygwin's telnet client and a commercial client.

you could try ssh; you do know that telnet has no security at all! even your passwords are sent in plain text! as simon said it looks like 'a character encoding problem' on the windows end

I need to use telnet. I am interested in a solution to the problem with telnet.

** DELETED ** - Going to re-post as new question as the problem isnt telnet specific.

I have to face the same problem when using windows telnet client, but i have not find out the solution.

csea, I found a workaround. It seems related to the en_US.UTF-8 locale.

If I choose

en_US.iso8859

or

en_UK.UTF-8
en_UK.iso8859

the problem goes away.

So what I did to avoid this problem was in /etc/profile I added

LANG=en_UK.UTF-8 export LANG

Mehuge:
Thank you for your help,
in the file /etc/sysconfig/i18n
LANG＝en_US.UTF-8,then it works very well.
when I typed "locale" in redhat as 4 ,the result is
LANG="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL

when i input "man gcc",it display normally,so en_US.UTF-8 is ok.

if you set your system as the following ,the problem will still exists.so
only adding "export LANG="en_US.UTF-8"" to the file ".bashrc" will be unable to solve the problem.

LANG=en_US.UTF-8
LC_CTYPE="zh_CN.GB2312"
LC_NUMERIC="zh_CN.GB2312"
LC_TIME="zh_CN.GB2312"
LC_COLLATE="zh_CN.GB2312"
LC_MONETARY="zh_CN.GB2312"
LC_MESSAGES="zh_CN.GB2312"
LC_PAPER="zh_CN.GB2312"
LC_NAME="zh_CN.GB2312"
LC_ADDRESS="zh_CN.GB2312"
LC_TELEPHONE="zh_CN.GB2312"
LC_MEASUREMENT="zh_CN.GB2312"
LC_IDENTIFICATION="zh_CN.GB2312"
LC_ALL=zh_CN.GB231

csea, I have LANG=en_US.UTF-8 in /etc/sysconfig/i18n and I get the problem unless I reset LANG to something other than en_US.UTF-8 when running gcc/man etc.

My /etc/sysconfig/i18n is:

LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
SUPPORTED="en_US.UTF-8:en_US:en"

locale reports:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

man and gcc give me the described problem:

If I change /etc/sysconfig/i18n to

LANG="en_UK.UTF-8"
SYSFONT="latarcyrheb-sun16"
SUPPORTED="en_UK.UTF-8:en_UK:en"

locale now reports

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_UK.UTF-8
LC_CTYPE="en_UK.UTF-8"
LC_NUMERIC="en_UK.UTF-8"
LC_TIME="en_UK.UTF-8"
LC_COLLATE="en_UK.UTF-8"
LC_MONETARY="en_UK.UTF-8"
LC_MESSAGES="en_UK.UTF-8"
LC_PAPER="en_UK.UTF-8"
LC_NAME="en_UK.UTF-8"
LC_ADDRESS="en_UK.UTF-8"
LC_TELEPHONE="en_UK.UTF-8"
LC_MEASUREMENT="en_UK.UTF-8"
LC_IDENTIFICATION="en_UK.UTF-8"
LC_ALL=

and man and gcc work (display quotes), however interestingly:

# man gcc

displays sequences like <E2><80><98><E2><80><98>

so it clearly isnt the proper/full solution.

Setting LANG unfortunatly breaks yum too - perhaps I need to re-init yum with the new LANG setting. I have to set LANG back to en_US.UTF-8 to get yum to work at present.

So... I still seek a proper solution to this problem (bug?) in FC4.

I found this article describes my exact problem:

http://www.redhat.com/archives/fedor.../msg03572.html

Sadly there is no reply to that thread and therefore no solution presented.

Did a bit more experimenting and have found that:

gunzip < /usr/share/man/man1/gcc.1.gz | groff -Tutf8 -mandoc | more

exhibits the problem and

gunzip < /usr/share/man/man1/gcc.1.gz | groff -Tascii -mandoc | more

doesnt. Basically, the extra characters we are seeing are the utf8 encoding:-

http://www1.tip.nl/~t876506/utf8tbl.html

and our terminals (windows telnet, cygwin ssh etc) do not support or process UTF8 so they display the raw charcter sequences.

With this in mind, I looked at changing /etc/man.config to change the groff command to us -Tascii instead however I didnt have any success, it seemed regardless of what I put in /etc/man.config for the commands, when I type man gcc or whatever, I still see the UTF8 encoded sequences. Grr..

So. I am back to setting LANG=en_UK.iso8859 but now I set this as the system default in /etc/sysconfig/i8n.

Now I need to try and fix yum which does not like the new locale:

Traceback (most recent call last):
File "/usr/bin/yum", line 29, in ?
yummain.main(sys.argv[1:])
File "/usr/share/yum-cli/yummain.py", line 67, in main
locale.setlocale(locale.LC_ALL, '')
File "/usr/lib/python2.4/locale.py", line 381, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting

Your os is fedora core 4,my os is redhat advanced server 4,Maybe the solution can't work well in your PC.

the file /etc/sysconfig/i18n in your pc is
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
SUPPORTED="en_US.UTF-8:en_US:en"

If you change /etc/sysconfig/i18n to

LANG="en_UK.UTF-8"
SYSFONT="latarcyrheb-sun16"
SUPPORTED="en_UK.UTF-8:en_UK:en"

locale now reports
locale: Cannot set LC_CTYPE to default locale: No such file or
directory
locale: Cannot set LC_MESSAGES to default locale: No such file or
directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_UK.UTF-8
LC_CTYPE="en_UK.UTF-8"
LC_NUMERIC="en_UK.UTF-8"
LC_TIME="en_UK.UTF-8"
LC_COLLATE="en_UK.UTF-8"
LC_MONETARY="en_UK.UTF-8"
LC_MESSAGES="en_UK.UTF-8"
LC_PAPER="en_UK.UTF-8"
LC_NAME="en_UK.UTF-8"
LC_ADDRESS="en_UK.UTF-8"
LC_TELEPHONE="en_UK.UTF-8"
LC_MEASUREMENT="en_UK.UTF-8"
LC_IDENTIFICATION="en_UK.UTF-8"
LC_ALL=

The reason is that the file /etc/sysconfig/i18n includes
SUPPORTED="en_US.UTF-8:en_US:en"
but en_UK.UTF-8 is not in the list of SUPPORTED="en_US.UTF-8:en_US:en".you must install it
