Question: dealing with \u0000 in strings from jerry_string_to_utf8_char_buffer / jerry_string_to_char_buffer

[martijnthe]

I realize this is not a JerryScript specific question, but I was wondering what people's approaches are towards dealing with strings from JS when they have a \u0000 unicode code point(s) in them. This ends up being encoded as a 0x00 byte, which happens to be the "terminator" of a C string as well.

I can imagine this being a source of bugs, esp. if assumptions are made in the C code w.r.t. the length given by jerry_get_(utf8_)string_length() vs strlen()/strlen_s().

Some approaches I can think of to deal with this:

• Don't use anything from <string.h>, instead use a proper utf8 library to deal with strings that only takes in string data in the form of a pointer + length.
• Truncate: just use the first 0x00 as the end and wipe all data after it just to be sure.
• ...
