I recently came across an article where a sinologist complained of not being able to understand the use of the character 㫬 in the following sentence:

> 
> 彪亦是南人。唯有中大夫楊元愼、給事中大夫王㫬是中原士族。
> 
> 
> 

The article describing the sinologist's troubles identifying the reason for this character being in the sentence follows:

Ever curious, I wondered if somebody here may be able to answer as to why this character is used in the sentence? And which of the alternative pronunciations: xuan, shun, xun, or something else would be used to say it?
