+### Using the configuration under Cygwin within Mintty
+

+
+It is possible to use this configuration under Cygwin within Mintty, however
+support for Unicode symbols and emojis lacks behind Mac and Linux.
+
+Particularly, Mintty's text rendering is implemented with GDI which has
+limitations: 
+
+- color emojis are only available through DirectWrite starting with Windows 8.1
+- display double width symbols, like the battery discharging symbol indicator
+  (U+1F50B) is buggy
+  
+As a consequence, under Cygwin, the battery charging (⚡ U+26A1) status indicator
+is rendered as a monochrome lightning bolt instead of a colorful emoji while the
+discharging (🔋 U+1F50B) one is simply disabled.
+
+Also, to get the battery charging status indicator displayed properly, you have
+to use [font linking]. Open `regedit.exe` then navigate to the registry key at
+`HKEY_LOCAL_MACHINE–\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink`
+and add a new entry for you preferred font to link it with the Segoe UI Symbol
+font.
