Some target platforms of SAPUI5 impose technical restrictions on the naming or structure of resources (files).For this, rules for file names and encoding have been introduced.
When developing content for SAPUI5, adhere to the following rules:
Folder names must not contain spaces (SAP HANA ).
To avoid issues with the SAPUI5 module loading and with URL handling in general, resource names should not contain spaces.
Single folder names must not be longer than 40 characters (ABAP).
Two resource names must not only differ in case (ABAP, some J2EE servers).
Avoid non-ASCII characters in resource names.
