Transliteration of Sanskrit I'm looking for resources on transliterating Sanskrit into Mandarin Chinese. Not necessarily just Buddhist terms, but a greater variety of Vedanta philosophy terms. 
(I have seen online, A Dictionary of Chinese Buddhist Terms by Soothill.)
I'm guessing that there is not a standardized system, but that certain terms have become standardized throughout history. 

For example:
ब्रह्मन् (Brahman (/brəhmən/)

Google translate gives: 婆罗门 (Póluómén) when attempting to translate the "Brahman", but I'm sure that is incorrect. I'm uncertain whether this particular term/concept is used in Buddhism (I know it's a Hindu concept), therefor I don't know if it would have been transliterated into 汉语.
The term, 婆羅門, has been used in China for at least 1500 years.

OLDict lists a few dictionaries. All of them transliterate "Brahman" as "婆羅門".

There are some Sanskrit-Chinese translations in 《大正藏》54, which can be downloaded in the pdf format. The script of Sanskrit is the Siddham (悉曇體), not the Devanagari (天城體).
