c++ - Matching a single line comment in QSyntaxHighlighter with QRegularExpression

Question

I'm trying to highlight single-line comments in VBScript using QSyntaxHighlighter in Qt 5.14.2. All example code I was able to find uses QRegExp instead of QRegularExpression, where a simple pattern like '[^ ]* or '.*$ seems to do the job. However, this doesn't work with QRegularExpression (which is required by QSyntaxHighlighter) and both of these match everything following ' including all newlines. What am I doing wrong?

Relevant code:

auto regexOptions = QRegularExpression::CaseInsensitiveOption;
HighlightingRule rule;
rule.pattern = QRegularExpression(QStringLiteral("'[^
]*"), regexOptions);
rule.format = format_SinglelineComment;
highlightingRules.append(rule);

Update: Turns out this is not an issue with regex, but rather with encoding. When I retrieve the TextEdit contents via ->toPlainText().toStdString(), I get a properly formatted string with for line breaks. If I take the text being passed to highlightBlock and do .toStdString() on it, I get a۬ instead of , indicating an encoding issue. Any ideas how to solve it?
