[4.26p4] Regression - decimal point divisor with coma, not point

Issue reproducible in any editor in any input text field. Steps to reproduce in Material Editor:

  • Open any Material in Material Editor
  • Create Constant node
  • In Details Panel enter “0.2” in Value (notice point between 0 and 2)
  • Result: Value is 1.0
  • Expectation: Value is 0.2
  • Enter “0,2” (notice coma instead of point!)
  • Result: Value is 0.2

It works fine in UE4 4.25.4, looks like a regression in text parsing

the issue is not reproducible in 4.26p5. release notes:

Fixed! UE-101455 Fallback for decimal separator seems not to work anymore

please close this ticket.
