The [`ssub`](reference-dsl-builtin-functions.md#ssub) function exists precisely for this reason: so you don't have to escape anything.
The
[`ssub`](reference-dsl-builtin-functions.md#ssub) and
[`gssub`](reference-dsl-builtin-functions.md#gssub)
functions exist precisely for this reason: so you don't have to escape anything.
The `ssub` and `gssub` functions are also handy for dealing with non-UTF-8 strings such as Latin 1, since Go's
`regexp` library -- which Miller uses -- requires UTF-8 strings. For example:
<pre class="pre-highlight-in-pair">
<b>mlr -n put 'end {</b>
<b> name = "Ka\xf0l\xedn og \xdeormundr";</b>
<b> name = gssub(name, "\xde", "\u00de");</b>
