+has-unicode
+===========
+
+Try to guess if your terminal supports unicode
+
+```javascript
+var hasUnicode = require("has-unicode")
+
+if (hasUnicode()) {
+  // the terminal probably has unicode support
+}
+```
+```javascript
+var hasUnicode = require("has-unicode").tryHarder
+hasUnicode(function(unicodeSupported) {
+  if (unicodeSupported) {
+    // the terminal probably has unicode support
+  }
+})
+```
+
+## Detecting Unicode
+
+What we actually detect is UTF-8 support, as that's what Node itself supports.
+If you have a UTF-16 locale then you won't be detected as unicode capable.
+
+### Windows
+
+Since at least Windows 7, `cmd` and `powershell` have been unicode capable.
+As such, we report any Windows installation as unicode capable.
+
+
+### Unix Like Operating Systems
+
+We look at the environment variables `LC_ALL`, `LC_CTYPE`, and `LANG` in
+that order.  For `LC_ALL` and `LANG`, it looks for `.UTF-8` in the value.
+For `LC_CTYPE` it looks to see if the value is `UTF-8`.  This is sufficient
+for most POSIX systems.  While locale data can be put in `/etc/locale.conf`
+as well, AFAIK it's always copied into the environment.
