Unicode Font Support in LabVIEW Real-Time

Issue Details

Can I install Unicode fonts (e.g. Cyrillic) to be used in LabVIEW Real-Time VIs on Real-Time targets (e.g. cRIO Controllers with NI Linux RT)?

Solution

Unfortunately, at the moment, LabVIEW Real-Time on Linux does not support Unicode encoding. Therefore, using Unicode-encoded characters, such as Cyrillic characters, will not work.

Refer to our recommendations below:

• Generally, we advise avoiding using a Front Panel on Real-Time (RT) targets in order to improve VI performance and maintain determinism. Instead of using Embedded UI or a Remote Front Panel, you can instead have a RT VI with no front panel, which shares data to a Host VI (running on a PC).
  • Part 5 (Sending data from RT) and Part 6 (Displaying data on Host VI) of the following Tutorial describe how to use Network Streams to send data from the RT VI (RT target) to the Host VI (PC).
  • Additionally, besides Network Streams, you can use other Remote Communication Methods. 
• For static text (such as Front Panel labels, instructions, etc.) you can paste images (PNG, JPG) onto the Front Panel or Block Diagram.
• You can control Front Panels of RT target VIs using a Remote Front Panel, an alternative to Embedded UI. If the LabVIEW Real-Time application's Front Panel is rendered by a Windows connection, then Windows can render Unicode text correctly.
