ubuntu, unrecognized characters...


I’m still pretty much a noob when it comes to ubuntu/linux and have a strange problem.
For some reason the arduino-IDE doesn’t recognize the ’ and " characters while typing.

When using other applications (gedit, open office, terminal etc. ) I have no problems.

I’ve one machine using Ubuntu 12.10 as single OS and another one running Lubuntu 12.10 under oracle VM on an XP-machine, both show the same behaviour.

Does anyone know what I can do to fix it ?

What do you mean? You hit a quote and nothing appears on the screen?

Yes, and I found 3 more missing characters, ascii 94, 96 and 126 ( ` , ^ and ~ ). Numbers of the first two are 34 and 39 ( " and ').

I wonder whether it has something to do with the language chosen in my OS(es), Dutch.
(we use US-qwerty keyboards btw.)

The language uses a few special characters like éèôëõáàï etcetera and to create one, I normally need to hit one of the missing characters followed by the letter it was used for. If I only want the special character, “like this”, I need to hit it, followed by a space or other… ünmergeable character.

Normally nothing shows on screen untill I hit the second character, but in arduino ubuntu the screen stays empty untill the third hit (of a non-special character) and it never shows the result of the first two.

Although remembering what all those numbers without explanation mean may be difficult at first, it might save me some flash on my duinos :slight_smile:

Luckily the PC in my hobby shed is a dual-boot system and powerful enough to run virtual machines though, so it’s no real problem.

I think it is the Dutch language. Try the ALT method of entering those characters. Insure the Num Lock is selected on your keyboard. Then hold down the ALT key and type the character number on the numeric keypad, then release the ALT key. It works with the special characters on my keyboard, like ¡ and ñ for Spanish.

A Google search found this page: http://tools.oratory.com/altcodes.html

Could indeed be language related, strange thing is that most other Ubuntu programs have no problems recognizing those characters. Since Arduino runs using Java I wonder whether it may be java - related. Typing ALT-nr apparently doesn't work using ubuntu.

Any way, thank you both for responding.

I hoped it might have been a known problem. For now I'll just use windows, maybe I'll look into it later when my Linux-skills are a bit better.
