Perspective Input cannot handle ~ (tilde) character

Ignition

Ignition perspective Text Input doesn't seem to except the ~ (tilde) character in any text input field.

We are using a barcode scanner that emulates a keyboard (no prefix or suffix) and are trying to paste into in input field on which we are running a change script on.

For some reason, whenever we scan a tilde character, it gets replaced with a - character.

It is behaving almost like the tilde character is escaping something.

Is there a way to modify the text input to allow the ~ character to be typed into it?

I'm able to enter ~ fine in text areas/text fields on our demo page:

Ok, it turns out it is tilde, if we zoom in it magically transforms into tilde again.

However, copy and paste into url bar of the same size reveals that the tilde doesn't render correctly at the same size.

PGriffith, can you confirm this happens on yours as well?

Still recognizably a tilde for me, MacOS running Chrome on a 4k monitor, no matter how far I zoom in or out:
(OS scaling plays havoc with screenshots; the first is less than half an inch real size, the latter is gigantic)

Do you get the same rendering behavior:

  1. In an incognito/private browsing session/with all extensions disabled on the same computer?
  2. On a different browser on the same computer?
  3. On a different monitor on the same computer?
  4. On a different computer in the same facility?
  5. On a different device type entirely (e.g. an android phone instead of an iphone instead of a desktop computer)?

And so on. I understand you're trying to fix the core issue on wherever you've got these barcode scanners hooked up, but eliminating variables is going to be the key to figuring out where the problem actually lies.

I guess my question is that regardless of how it's rendering on the screen, is the change script not functioning properly? You could always log to the logger to make sure it's reading properly, but if it just looks more like a dash vs a tilde on the screen, does it really matter since it's a barcode scanned value anyway?

Interesting. Ok, interesting. All my stations are windows(1080p) and this we thought was leading to another issue.

Thanks for the follow up.

Yes, you are right, I thought this was leading to another issue, but it is not the case.

Thanks for the follow up.
