It's "automatic", see https://www.w3.org/International/articles/inline-bidi-markup/uba-basics https://www.w3.org/International/articles/inline-bidi-markup... and https://unicode.org/reports/tr9/ https://unicode.org/reports/tr9/ However that algorithm has a couple of flaws in mixed left and right ordered text, and a couple of control characters have been introduced to solve the issue: https://www.w3.org/International/questions/qa-bidi-unicode-controls https://www.w3.org/International/questions/qa-bidi-unicode-c... Could play a bit in https://www.babelstone.co.uk/Software/BabelPad.html https://www.babelstone.co.uk/Software/BabelPad.html to see how things work.
