Issues in ION Setup when saving Site Or Meter with foreign language characters in name

Issue:

When creating or editing a Site or Meter in ION Setup and saving a name that includes foreign-language characters (for example: é, ñ, ø, ç, or non-Latin scripts):

ION Setup 2.0: May stop responding (hang/freeze) during the save operation.

ION Setup 3.0: Save completes, and the application continues to work; however, the unsupported characters may display as question marks (?).

Product Line:

ION Setup

Environment:

• ION Setup
• Action: Adding or editing a Site or Meter and then saving the record

Cause:

ION Setup does not reliably support storing or rendering foreign-language / extended Unicode characters in Site or Meter names.

• In ION Setup 2.0, this limitation can cause the application to become unresponsive when attempting to save.
• In ION Setup 3.0, the save typically succeeds, but unsupported characters may be converted to ? (loss of character fidelity).

Resolution:

Use only standard ASCII characters when naming Sites or Meters.

Recommended naming guidance:

• Use letters A–Z, a–z, digits 0–9, and common keyboard punctuation (e.g., -, _, .).
• Avoid accented characters (e.g., é, ü, ñ) and non-Latin scripts.

Example (preferred):

• Building_A_North
• Meter-3_Main
