+# SC1077: For command expansion, the tick should slant left (` vs ´).
+
+
+### Problematic code:
+
+    echo "Your username is ´whoami´"
+
+### Correct code:
+
+    echo "Your username is $(whoami)" # Preferred
+    echo "Your username is `whoami`"  # Deprecated, will give [SC2006] 
+
+### Rationale:
+
+In some fonts it's hard to tell ticks apart, but Bash strongly distinguishes between backticks (grave accent `` ` ``), forward ticks (acute accent `´`) and regular ticks (apostrophe `'`). 
+
+Backticks start command expansions, while forward ticks are literal. To help spot bugs, ShellCheck parses backticks and forward ticks interchangeably. 
+
+### Contraindications
+
+If you want to write out literal forward ticks, such as fancyful ascii quotation marks:
+
+    echo "``Proprietary software is an injustice.´´  - Richard Stallman"
+
+use single quotes instead:
+
+    echo '``Proprietary software is an injustice.´´  - Richard Stallman'
+
+To nest forward ticks in command expansion, use `$(..)` instead of `` `..` ``.
