Keyboard characters become "messed up"

Hi,

My MATLAB works perfectly fine, but after some time some keyboard characters become "messed up". For example:

    / results in é,  
    " results in `,
    < results in ',
    ? results in É

The only way to fix it seems to be to restart MATLAB.

Did anyone else encounter this problem? I'm running MATLAB R2011a on Windows 7.

I would greatly appreciate any advice.

Thank you, K

I'm running Matlab 2014a on Ubuntu linux trusty over a NoMachine NX remote session, and after some time, typing behaves erratically. For example, typing "asd" will produce "as", and then the cursor will select a few characters in the editor, instead of producing a "d". Typing another character will replace the spuriously selected ones.

Matlab needs to be restarted to correct the problem. Searching around, somebody suggested creating a java.opts file with the line

-Dsun.java2d.pmoffscreen=false

but this doesn't fix anything in this particular case.

Similar problem here, but for me it only happens in the Editor (everything works fine in the Command window) and with the character ~

Hey K,

I had the same problem, whenever i started my Matlab and entered keyboard characters, i had completely different stuff in the command window. Here is how it worked and boy is took me 6months to figure out(hahaha, how dumb i am).

I bought my laptop in China, so the regional settings where set to China. So 1. go to control panel 2. regional settings(US) 3. change the region and also the language setting(US English). 4. Save the changes.

Remember, even though I could write and type in English before i changed the settings, AFTER changing it it still worked and WORKED IN MATLAB. Good luck

Thanks Kwaku, I will try this out...

I had the same problem. Though other software worked fine, so it was not an issue with system settings. I solved pressing several times (not sure how many). Shift + Alt + AltGr

Thanks, I had this problem, and your comment helped me to solve it!!

Do you happen to be using Simulink? I'm wondering if you are encountering an slcharacterencoding(), possibly in some model you are running?

[K]

Hi Walter,

Thanks for your answer. No, I'm not using Simulink... Just fairly straightforward data analysis (file I/O, plotting, fft, etc).

Did it happen in MATLAB Command Window or Editor? Before and after the problem happen, could you check menu File->Preferences->Keyboard, Fonts to see if there is any obvious change?

Probably it's better to call TMW tech support up and run a WebEx session to show them.

[Ksenia]

Thank you for the suggestions. This happens both in the Command Window and the Editor. I will check the Fonts menu for any obvious changes the next time this happens (it's pretty unpredictable).

Does the problem appear in other applications also, e.g. external editors? Then you could have typed the shortcut for changing the keyboard layout. (wild mass guessing...)

[K]

No, this only happens in Matlab! And gets back to normal after restarting Matlab.

[Jan]

@K: I had problems after installing a new JRE in Matlab 6.5: Everything worked fine except for the curly braces in the command window. Are you experimenting with Java?

[K]

No, I haven't made any changes in Java recently.

[Fangjun Jiang]

@Jan, your keyboard latency problem is coming back!:)

I had the same problem since last night. It seems to be the problem of the Answers website.

[Jan]

@Fangjun: I've tried to create a thread with the subject "Broken web interface of Answers" etc, but without success. I got just the error message... It would be helpful, if this problem is announced anywhere.

Similar problem here, running MATLAB 2016a on a Windows7 machine. Characters don't print properly in Command Window and Editor. Can't seem to type any brackets ('[]') which is very unsettling when using MATLAB!

Problem started yesterday. I checked regional settings and everything seems fine. Same with MATLAB preferences...

Anyone found a way out of this?
