Symfony2 Yaml Dumper单引号转义

Question

I've got some csv translations that are transformed and written into messages.fr.yml with Symfony\\Component\\YamlDumper, and on strings like d'achat it becomes 'd''achat' .

I've done some debugging and discovered that the string is recognized as the one that needs escaping:

preg_match('/[ \s \' " \: \{ \} \[ \] , & \* \# \?] | \A[ \- ? | < > = ! % @ ` ]/x', $value)

and then escaped with the following code:

return sprintf("'%s'", str_replace('\'', '\'\'', $value));

I already tried using function addslashes before the debugging, but this escaping is not recognized.

So I'd like to know the opinion of the Symfony community: is it a bug or is it a feature? Should I report it and fix or just check my inputs and replace single quotes (') with apostrophe (')?

In YAML, a double quote ('' - 2 singles) is how a single ' quote is escaped.

This is not a bug & the double quotes are automatically converted to single quotes by the YAML parser.
