Hi, a client is using nb_NO (Norsk Bokmål) Locale on a Windows Server machine and the produced FFS filename is incorrect. They are using FME Form 2024.2.3.0.I have tested same om my machine Windows 11, FME Form 2025.1.1.0 - build 25615. I want to produce a filename “t2_æøå”.FFS (where æ, ø and å are Norwegian alphabet letters)using en_US Locale the produced file is t2_æøå.FFS using nb_NO Locale the produced filename is t2_Ã¦Ã¸Ã¥. FFSI repeated the test wiriting to Esri Shapefiles - and both Locale will give the result t2_æøå.shp. Seems like the FFS writer have an issue with Locale. Might be a known issue but I was not able to find it. Thanks

Hi, a client is using nb_NO (Norsk Bokmål) Locale on a Windows Server machine and the produced FFS filename is incorrect. They are using FME Form 2024.2.3.0.

I have tested same om my machine Windows 11, FME Form 2025.1.1.0 - build 25615. I want to produce a filename “t2_æøå”.FFS (where æ, ø and å are Norwegian alphabet letters)

using en_US Locale the produced file is t2_æøå.FFS
using nb_NO Locale the produced filename is t2_Ã¦Ã¸Ã¥. FFS

I repeated the test wiriting to Esri Shapefiles - and both Locale will give the result t2_æøå.shp. Seems like the FFS writer have an issue with Locale. Might be a known issue but I was not able to find it. Thanks
