Question:
Why are fullwidth and halfwidth supported in Account Search on iRep but not on WinModern?
Account Search on WinModern:

Account Search on iRep:

Answer:
This is expected.
Corresponding Accounts can be retrieved by searching the same keywords in halfwidth or fullwidth format on iRep. If the Account name is entered as halfwidth to the database in WinModern, searching in fullwidth does not return the Account (and vice-versa).
IOS has its own special handling for the search that automatically lets users search both ways. However, Windows does not have that built-in capability.
