Function Documentation

canUseBlockScalar()

bool canUseBlockScalar ( StringRef S )

static

A literal block scalar has no escapes, so it can only hold printable characters, tab and line feed.

That rules out C1 controls, and NEL, LS and PS, which YAML 1.1 readers take as line breaks. Invalid UTF-8 stays in the block, since yaml::escape would drop it. Readers take the indentation from the first non-empty line, so that line cannot start with a space.
