[Solved]I'm puzzled and bewildered...

[cdbc]

Hi
edit: See last post for explanation & fix
So, I'm fiddling with console & unicode in forked TTextCanvas code from @Warfley... Pretty nice 
Now here's the completely 'Bonkers' situation, that I'm looking at:
In KDE's Konsole it's working great =^
In XTerm ...NOT so much, have a 'looksee' at the attached pictures...
What I don't understand is this: Standard codepage on Linux is UTF8, here too, so why the H*ll aren't the two different terminal-emulators agreeing?!?

Any input on this is greatly appreciated...

Regards Benny

Benny, what does export tell you? (forgot the grep for it) Analize the export

I'll have to have a longer look, to see if something 'glares' at me... 
Thanks for the tip mate =^

Hi
...And there lies the damned dog buried: System Locale 
Although being a Dane \o/ I utterly HATE Danish on my desktop!!! 
Thus I've been running a 'bastard' system in English with just a few pinpointed Danish localisations - currency, numbers and clock etc...

So, after sifting through the 'export's of my system, it suddenly hit me 
:: English speaking have no real need for full UTF8 or Unicode, i.e.: no æøå ÆØÅ Ü Ö Ä ö ü ä Ñ ñ etc... So apps sometimes defaults to CP 8859-1 which maps pretty close to utf8 & ascii -- Close, but no cigar!
Why the box-characters fall into that category, I dunno!

I thought to myself, WTH I'll give it a shot and install Danish locale on my system   ...and Lo and Behold => NOW IT WORKS FLAWLESSLY 
It turns out that 'Konsole' doesn't give a flying F*CK about system locale and just use UTF8 / Unicode, period.
Whereas the other terminal emulators are staying loyal / true to the system locale, with a potential fallback to 8859-1   ...Who'd have thunk it 

So now I'm left with 'nudging' every application into using English 
Oh Well, could have been worse, right 
Screenshot from XTerm attached...
Thanks Thaddy

Just out of curiosity, did you try UXTerm?

[cdbc]

Hi
Nope. I have 4 different terminals to work with on a daily basis, all now working great, no need for more...
- Konsole
- Terminology
- QTerminal
- XTerm
Regards Benny

[tetrastes]

UXTerm is just XTerm launched with some parameters fitted for UTF-8 locale. It usually presents along XTerm.
