Subject: gvedit MdiChild::saveFile: disable explicit UTF-8 saving with Qt ≥ 6
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7d8ac449acd5b417dd7b60c73a0777c84757ea55;p=graphviz

gvedit MdiChild::saveFile: disable explicit UTF-8 saving with Qt ≥ 6

From Qt6 onwards, `QTextStream` is in UTF-8 by default:¹

  By default, QStringConverter::Utf8 is used, and automatic unicode detection
  is enabled.

Gitlab: #2233
