135/**
136 * ctk_source_utils_escape_search_text:
137 * @text: the text to escape.
138 *
139 * Use this function to escape the following characters: `\n`, `\r`, `\t` and `\`.
140 *
141 * For a regular expression search, use g_regex_escape_string() instead.
142 *
143 * One possible use case is to take the #CtkTextBuffer's selection and put it in a
144 * search entry. The selection can contain tabulations, newlines, etc. So it's
145 * better to escape those special characters to better fit in the search entry.
146 *
147 * See also: ctk_source_utils_unescape_search_text().
148 *
149 * <warning>
150 * Warning: the escape and unescape functions are not reciprocal! For example,
151 * escape (unescape (\)) = \\. So avoid cycles such as: search entry -> unescape
152 * -> search settings -> escape -> search entry. The original search entry text
153 * may be modified.
154 * </warning>
155 *
156 * Returns: the escaped @text.
