Requirement of UTF-8 string for description field of attribute

[m-sb]

Hi,

When writing attribute to the blockmodel and adding description getting error like "required utf-8 string type". This is not consistent.

std::string str = "description data";
attribute.description = str.c_str();

The above code works fine sometimes. but sometimes getting error.

could you help on this @Tim-Evans-Seequent .

Thanks in advance.

That error is likely because your description is not in UTF-8 encoding. ASCII strings will also work, as ASCII is a subset of UTF-8. Other common encodings, like Windows-1252 for example, aren't compatible, and you'll need to convert those strings to UTF-8 before using them.

Unfortunately, C++ has poor support character encodings. You'll need a third-party library to handle it, and I can't give much advice on that.
