[php-src] Issue #8586: MessageFormatter seems to not translate correctly when having apostrophe before the translation key

Issue: https://github.com/php/php-src/issues/8586 Author: andreisha ### Description Hello :) Thanks a lot for everything you do. I came across this issue that seems like a bug to me. I looked if there were other similar bugs opened but I didn't find one. The following code: ```php <?php echo msgfmt_format(msgfmt_create("fr", "Name - '{name}' \n"), ["name" => "Martin"]); echo msgfmt_format(msgfmt_create("fr", "Name - ''{name}'' \n"), ["name" => "Martin"]); echo msgfmt_format(msgfmt_create("fr", "Name - ' {name} '"), ["name" => "Martin"]); ?> ``` Resulted in this output: ``` Name - {name} Name - 'Martin' Name - ' Martin ' ``` But I expected this output instead: ``` Name - 'Martin' Name - 'Martin' Name - ' Martin ' ``` Is this normal? Thanks! ### PHP Version 8.1 ### Operating System _No response_
