Subject: Only use utf-8-mac when iconv supports it
X-Git-Tag: 0.1.1^0
X-Git-Url: https://git.ladys.computer/Yseme/commitdiff_plain/f6ab0225fdd5a404fbd592b0d5c051f0cbea4135?hp=8a2cc5576e57c0097b434d9c2a706fc856e2ed3e

Only use utf-8-mac when iconv supports it

This should hopefully avoid needing device‐specific character set
configuration for repositories.
