|---|---|---|
\ | \\ | Always |
" | \" | Always |
' | \' | Always |
| Line feed (0x0a) | \n | Always |
| Carriage return (0x0d) | \r | Always |
| Characters from 0x00 to 0x1f, except listed above | \x## where ## is two hex digits | Always |
| Characters from 0x80 to 0xffff | \u#### where #### is four hex digits | If rawunicode suffix is not present (default) |
| Characters from 0x80 to 0xffff | Introduced in v5.1.23 Unchanged | If rawunicode suffix is present |
Introduced in v5.1.23 If the suffix rawunicode is present, Unicode characters above 0x80 (such as ß, ä, ñ or 🎄) will be passed through unchanged. Without the suffix, they will be substituted with \u codes, which was the default behavior before 5.1.23. Characters outside the Basic Multilingual Plane, such as 🎄 and other emojis, will be encoded as a UTF-16 surrogate pair, i.e. with two \u sequences.
