Improve superscript/subscript line spacing (leading)
Summary
The presence of superscripts or subscripts in a paragraph of text disrupts the line spacing (leading) of the paragraph. Using a fixed line spacing (Text Line Height = 100%) makes the situation much worse.
Detailed Description
In a Microsoft Word source document, a line of text with one or more superscript or subscript characters displays with the same line spacing as the remainder of the paragraph, but with the superscript (or subscript) characters displayed in the interstitial space between the lines.
The default display in WebWorks Help 5 places the superscript character on a line by itself and pushes the normal characters to the next line down. This produces an unsightly gap in the paragraph that looks nothing like the original text in the source document (see attached screenshot, top paragraph).
Defining a fixed line space (leading) in ePublisher (Text Line Height = 100%) should force the non-superscripted characters into the same line as where they would display if the superscript were not present, with the superscript displayed in the empty space above the line. Instead, the superscript is displayed in line, and all of the non-superscripted text displays in a subscript position (see attached screenshot, bottom paragraph).
Although using a character style with HTML tag='pre' reduces the problem by making the superscript text smaller, the underlying defect still shows through.
Use Cases
Any multi-line paragraph of text that includes one or more superscript or subscript characters.
