Replace with regular expressions on MacOS

[nachocho]

Hi, I am not sure if what I am observing is a bug, a limitation of the regular expressions replace feature, or if I am missing something when trying to use the feature.

2 things that do not work for me:

1. Trying to set the style of subtitles using a regex. (This I think may be a limitation)

Take as an example the following subtitle entry (as plain text):

270
00:14:41,520 --> 00:14:44,840
<Soy Jeremy. Jeremy Parks. 
<El tonto que te chocó de atrás. 

Where some lines start with "<" for some weird reason, but by looking at the context in the video those lines should be in italics. So I want to use a regular expression for replacing such as:

Original value: "^<" New value: "<i>"

But the regular expression just inserts the text "<i>" as part of the subtitle instead of changing the style to italics.

2. Trying to use the new line character "\n" in the New value field. (This one looks like a bug to me)

Take as an example the following subtitle entry (in plain text):

553
00:28:15,020 --> 00:28:17,300
así que, no podemos ver su cara.
- ¿Y Corinne?

Where the entry is about a dialog between two people, so I want to fix it by checking if any entry has a hyphen next to a new line character but no hyphen at the start of the text, and inserting the hyphen at the start of the text so to get this result:

553
00:28:15,020 --> 00:28:17,300
- así que, no podemos ver su cara.
- ¿Y Corinne?

The regular expression values for the replace I am using are:

Original value: "^ *([^-]+)\n- *([^-]+)$" New value: "- $1\n- $2"

Which gives me the following result (also in plain text):

553
00:28:15,020 --> 00:28:17,300
- así que, no podemos ver su cara.n- ¿Y Corinne?

Meaning that for some reason instead of inserting a new line character "\n" it is inserting just a "n" with no backslash.

If I test both the original text and the original value and new value in regular expressions 101, it gives me the result I expect in Jubler, which is:

553
00:28:15,020 --> 00:28:17,300
- así que, no podemos ver su cara.
- ¿Y Corinne?

Am I missing something in the values I am using for the replace?

Thanks!
