Reading UTF-8 Files in Labview

[SWEng21]

I need to read UTF-8 encoded files to display Chinese and Korean charaters I have fonts to display then and the files display correctly in notepad but loads garbage in Labview 8.0.1 can the Read Text File be configured to read UTF-8 encoding or is there another Vi that will work?

This is for a Multilingual App the needs to dynamically switch between English, Spanish, Chinese, and Korean when running not just when installed.

SWEng21,

If you aren't using XP, you can take a look at this thread, which provides some user vi's to decode most of unicode, but may have problems with special characters.

Thanks Rob_K,

Unicode will work, I can read the data and display it in strings, button text, and captions for each language.

Can I display unicode text in the window title?  I have not been able to get text rings, menu rings, or Comboboxs to display unicode text consistantly even when I use version 8.5.1.

LabVIEW is natively ANSCII, so I believe it is not available in rings since they point to actual references.  If there is a way, I am not aware of it.

I have got it to work in string displays and captions, as you have mentioned.

If you really needed a workaround, you could probably create a custom control with string indicators as the scrolling options...that would actually be impressive if you could make it work, but it would take a bit of effort.

Thanks, 

I can live with the ring and combo box in ASCII I have already made a Vi for conversions from Unicode to ASCII to display text from the Unicode file for these.

I also realized that none of the supplied Dialog pop up boxes can display Unicode text so I am creating custom Vis to workaround this also. This would be nice to have in future versions of LabView.

I am using Tabs and have set it to allow the captions to change but I do no see how to force/use unicode for the tab captions. The customer requires that tabs and text rings to be unicode compliant for Chinese and Korean.  Is there a way to make these work  in Labview??

Agreed. I have talked with some R&D folk about this, but feel free to also submit a product suggestion from our website.

For reading (and writing) UTF-8 encoded files see the VI attached to this message:
