+### Common Task: remove ANSI escape codes
+> :warning: This common task is still experimental.
+> If it does not work for you, please open an issue so that we can adapt the
+> code snippet.
+
+Some devices produce ANSI escape codes to enhance the appearance of output.
+However, this can make prompt matching difficult and some of these ANSI escape
+codes might end up in the resulting configuration.
+
+You can remove most [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Control_Sequence_Introducer_commands) using the following Ruby
+code in your model:
+```
+  # Remove ANSI escape codes
+  expect /\e\[[0-?]*[ -\/]*[@-~]/ do |data, re|
+    data.gsub re, ''
+  end
+```
+Explanation of the Regular Expression:
+- `\e\[`  : Control Sequence Introducer (CSI), which starts with "ESC [".
+- `[0-?]*`: "parameter" bytes (range 0x30–0x3F, corresponding to ASCII `0–9:;<=>?`)
+- `[ -/]*`: "intermediate" bytes (range 0x20–0x2F, corresponding to ASCII ` !"#$%&'()*+,-./`)
+- `[@-~]` : the "final" byte (range 0x40–0x7E, corresponding to ASCII ``@A–Z[\]^_`a–z{|}~).[``)

 ## Extending an existing model with a new command
 
 The example below can be used to extend the `JunOS` model to collect the output of `show interfaces diagnostics optics` and append the output to the configuration file as a comment. This command retrieves DOM information on pluggable optics present in a `JunOS`-powered chassis.
