This is patch to RSJ's cdfs.ifs v. 5.53 that allows to understand 
whole 255 char character table (including non-english letters) in file names.

I really don't know why RSJ team doesn't do this for years because this 
problem rises again in every release of RSJ.

Soluton is very simple: at the end of cdfs.ifs you can locate two incomplete 
characters table like this one (in hex, after 127th symbol):
7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7E7EFFADBD9CCFBEDDF5F9B8A6AEAAF0A9EEF8F1FDFCEFE6F4FAF7FBA7AFACABF3A8B7B5B6C78E8F9280D490D2D3DED6D7D8D1A5E3E0E2E5999E9DEBE9EA9AEDE8E185A083C6848691878A8288898DA18C8BD0A495A293E494F69B97A39681ECE798
All we must to do is replacement in both tables this sequence to correct 
continue of character table like this one (in hex, after 127th symbol):
808182838485868788898A8B8C8D8E8F909192939495969798999A9B9C9D9E9FA0A1A2A3A4A5A6A7A8A9AAABACADAEAFB0B1B2B3B4B5B6B7B8B9BABBBCBDBEBFC0C1C2C3C4C5C6C7C8C9CACBCCCDCECFD0D1D2D3D4D5D6D7D8D9DADBDCDDDEDFE0E1E2E3E4E5E6E7E8E9EAEBECEDEEEFF0F1F2F3F4F5F6F7F8F9FAFBFCFDFEFF
As you can see there's nothing too difficult to do.

I also include binary patch file in MDIFF format for RSJ 5.53 release. 
You can apply this patch to cdfs.ifs with MDIFF utility (located at 
http://hobbes.nmsu.edu/pub/os2/dev/util/mdf150.zip) by running 
"MPATH2.EXE cdwfs.MDF" in directory where your RSJ is installed.

With best regards,
