enable more character formatting

[ewa4boeker]

right now italic works fine but bold, underlines, teletype and others also become italic?!
(tested on document 1174 sequence 11 section 1)

@Jotunbane any rason? or do I get things wrong?

• seems the substitution wringfully make everything italic for now instead only <text:span text:style-name="Emphasis">. should be possible to fix with $xml->xpath()
• and custom styles on character lever could be defined in the template just like the paragraph styles where done.

todo:

• limit italic to <text:span text:style-name="Emphasis"> (prepared)
• fix bold for <text:span text:style-name="Strong_20_Emphasis"> (prepared)
• implement source (inline) for <text:span text:style-name="Source_20_Text"> (prepared)
• implement underlined for e.g. <text:span text:style-name="underlined"> (custom)
• implement underlined-double for e.g. <text:span text:style-name="underlined-double"> (custom)
• implement strike-through for e.g. <text:span text:style-name="strike-through"> (custom)
• implement blackened for e.g. <text:span text:style-name="blackened"> (custom)
• implement smallcaps for e.g. <text:span text:style-name="smallcaps"> (custom)
• others needed?
