Korean names don't transliterate if they contain punctuation

[scossu]

Reported from Jenna:

In korean_names, S2R:

도, 상록.
to, Sang Nok🜁75ŏk (The result should be: To, Sang-nok. )

도, 상록
to, Sang Rok (The result should be: To, Sang-nok )

도 상록.
To Sangnok🜁-75ŏk (The result should be: To Sang-nok. )

도 상록
To Sang-nok (This is correct.)

It looks like punctuation is interfering with the scanning of the characters.
