Хорошо, это странно. Последние несколько лет я использовал символ молнии Unicode в качестве подсказки в Powershell. Я только что получил новый ноутбук и переустановил все. Я запускаю Powershell с помощью Cmder, просто создаю резервную копию всего каталога в Dropbox и восстанавливаю его на свой новый ноутбук, поэтому ничего не нужно менять. Теперь моя подсказка - два удара молнии. Функция подсказки выглядит так:

Write-Host -ForegroundColor Yellow -NoNewLine "`n" ([char]0x26a1).ToString()

Когда я запускаю эту команду, я получаю:

Итак, в основном символ 0x26a1 - это два болта вместо одного. Та же версия Windows 10, та же версия Powershell, та же версия Cmder, все те же настройки. Что может заставить PowerShell отображать символы Unicode, как это? Есть также несколько других символов, которые удвоены (например, 26aa - два круга), но большинство символов в порядке (2601 - одно облако). Я также пробовал разные шрифты в терминале, но каждый удваивается. Какая часть Windows будет нести ответственность? Спасибо!
