Quotes are getting removed from string starting with "00" on dumping yaml file

[shekhar-dahiya5]

Hi,

We have used safeDump() method on our yaml file. Yaml file consist of some examples that starts with "00".
When we tried to dump the yaml file, string quotes were removed. Unfortunately something is not working as expected,

examples where quotes are removed -

Input -
accountNumber: "001408",
accountNumber: "00120451921"

Output -
accountNumber: 001408,
accountNumber: 00120451921

examples where quotes are not removed -

Input-
accountNumber: "00300300175747767"
accountNumber: "00167"

Output -
accountNumber: "00300300175747767"
accountNumber: "00167"

If we use only digits below 8 (octal digits), it work fine, quotes are not removed. (This should not be the expected behavior)
