Can I use hyphens, spaces and extra underscores inside UCS filename blocks, and how do tools split the optional UserCategory and VendorCategory parts?

Per the vendor-page text, hyphens carry meaning: a hyphen after the CatID starts UserCategory and a hyphen inside the FXName block ends an optional VendorCategory. ucs-tools says this makes the split ambiguous and resolves it structurally, while ucsrename's habit of turning spaces into hyphens would make an ordinary multi-word FXName parse as VendorCategory plus FXName under the vendor-page rule. This is a synthesis from secondary text and code; the official document was not read.
