哿

The title of this poem in the evidence is 《古意三首》. When we read this poem carefully, it's not hard to find out there are three parts based on the rhyme characters. The first part is 甕(옹)宋(송)洞(동)夢(몽), the second part is 隙(극)白(백)藥(약)獨(독) and the third part is 先(선)賢(현)全(전)年(년). The submitted character is in the second part. Notice that the real rhymes (vowels and the following consonants in the syllables) are different in Old Chinese, Middle Chinese (that means 平水韻 here) and Korean readings, maybe we should call it as 押鄰韻 (rhyme adjacently?). The previous verse “胡爲勞形役” is an interrogative question, so the verse with the submitted character should be the reply to the previous verse. This verse looks related to “哿矣富人，哀此惸獨。” in 《詩經·小雅·正月》. However, if we treated this character is the same as 哿 totally, the meaning is contrary to Confucian ideas and the spiritual style of this poem.

My suggestion to keep and encode this character as-is.

agree with Eiso.

KR does not agree to unify.
