Common questions
Does title case follow every style guide?
Not always. Different style guides handle small words such as articles and prepositions differently.
Does it affect Chinese text?
Chinese text has no letter case, so conversion mainly affects English and other Latin letters.
Does it change spacing?
The tool is intended to change letter case, not rewrite the text structure.
