Description

  • Issue Observed:
    • Default scanner configuration (Ctrl+]) worked in French (FR) environments but failed in English (EN) setups.
    • The discrepancy was due to keyboard layout and browser language interaction.
  • Investigation Steps:
    • Tested across FR and EN environments.
    • Verified behaviour using Notepad++ and Citrix HTML5 Receiver.
    • Confirmed that syncing the remote keyboard layout to FR resolved the issue temporarily.
    • Identified that the root cause was the scanner’s default key mapping.

Resolution

  • Updated the scanner configuration from Ctrl+] to an alternative sequence such as Alt+xxx.
  • After applying this change, scanning worked correctly in both FR and EN environments.
  • No code changes were required; the resolution was purely configuration-based.

Issue/Introduction

Issue with barcode scanning in Citrix HTML5 Receiver where the ASCII group separator character could not be transmitted correctly. The problem was linked to language-specific behaviour in the scanner configuration rather than a product defect.
