Camera raw 8.3.0.141 truncates file names

Question

This is a recent thing.
I open jpg images from bridge cs6 into camera raw and save new versions from camera raw into a new folder.
Our incoming file names contain important data but not all of the name is written when I save jpg from camera raw.
file name length seems to max out at 60 characters or so.
THIS WAS NOT THE CASE SOME MONTHS AGO IN THIS MACHINE.
Our folder names are long also but the combined path + filename length  rarely exceed 230 characters.
Our file naming system has worked for some years and photoshop does not truncate file names, only this latest camera raw.
This is on win 7  64 bit pro machine - our filenames do not need to be compatible with anything else whatever.
example of our file/folder naming lenghts on my win machine:
C:\AAliikkeet\02 xxxx oierjksinth\112255_ehhsyag somajrysen fgetrakunnan paievjerho_CO_10022014_til.73673\vlc\nietalahtn, naurvkustunr_bbseh syplamaiden syrdknhhar prifakehfo_IMG2722korjattu_cpy004_5000_02.jpg
the real names have been replaced with strings of corrensponding length so this long baby represents a long(ish) folder+filename combo in our systems.
This is a major new problem.
Any help appreciated - even the good old "use shorter file names, idiot" but that is not an option for me.
We are working in an industrial environment and systems  - including file naming have been working OK for some years and I cannot change our systems just to please my latest camera raw.

Answer 1

Thank you for your kind advice and interest in my problem.
I tested:
c:\in\v  -folder is the one that jpg is read
c:\in\vlc is folder that the camera raw saves jpg
original file name was:
HIETALAHTI, TENAVAMUSKARI_VAASAN SUOMALAISEN SEURAKUNNAN PÄIVÄKERHO_cpy004_5000_02.jpg
it is truncated into:
HIETALAHTI, TENAVAMUSKARI_VAASAN SUOMALAISEN SEURAKUNNAN P.jpg
I shortened the original file name and removed the scandinavian A with dots on top of it and the comma from ther file name:
HIETALAHTI TENAVAMUSK_VAASAN SUOMAL SRK PAIVAKERHO_cpy004_5000_02.jpg
truncates to:
HIETALAHTI TENAVAMUSK_VAASAN SUOMAL SRK PAIVAKERHO_cpy004_5.jpg
the scandinavian alphabet is not a problem (the file names are not always clipped in their position).but causes some extra truncating:
HIETALAHTI-TENAVAMUSKARI_VAASAN SUOMALAINEN PÄIVÄKERHO_CPY00.jpg turns into:
HIETALAHTI-TENAVAMUSKARI_VAASAN SUOMALAINEN PÄIVÄKERHO_CP.jpg
and
HIETALAHTI-TENAVAMUSKARI_VAASAN SUOMALAINEN PÄIVÄKERHO_CPY0.jpg into same
HIETALAHTI-TENAVAMUSKARI_VAASAN SUOMALAINEN PÄIVÄKERHO_CP.jpg
This is why I havent found a good rule in this.
In camera raw the whole file name shows under the preview image but  in saving the image the file naming example is truncated.
Even the longest of our file names worked flawlessly  for several years until maybe two weeks ago.
60 characters is top length that did not truncate in this testing
