The checks for whether a style should be opened/closed at the current character position are as follows: A variable entry contained the index of the currently active or potentially next active style. If the current character position coincided with the start of style[entry], the style was activated; this was followed by a check whether the current character position coincided with the end of style[entry]; if so, the style was deactivated and entry incremented. Afterwards the char was processed. The order of the checks leads to problems in case the endChar of style A coincides with the startChar of the next style (say B): Style B was never opened. When we are at said common position, the currently active style is A and so the start pos check does not succeed; but the end pos check does and it closes the currently active style A and increments entry. At the next iteration of the loop, the current character position is bigger than the start position of style B (which is style[entry]) and therefore the style is not activated. The solution is of course to first check for whether a style needs to be closed (and increment entry if it does) before checking whether the next style needs to be opened.
