Sections / paragraphs and acronym package

[Former user]

``` What steps will reproduce the problem? 1. Define a acronym, e.g.\acro{UML}{Unified Modeling Language} 2. Insert a section or a paragraph and reference acronym, e.g. \section{\acf{UML}} or \paragraph{\ac{UML}} 3. Run pdflatex and look at PDF.

What is the expected output? What do you see instead? Instead of the expected acronym output I get the output of a not found acronym, e.g. "uml!"

What version of the product are you using? On what operating system? This occurs in classic thesis template version 2.8 on Windows and Linux.

Please provide any additional information below.

When using the same acronym in continuous text, everything is fine. But pdflatex gives me the following warning, when using a acronym in sections or paragraphs: Package acronym Warning: Acronym `uml' is not defined on input line 286.

I guess there must be a implicit conversion to lowercase in sections / paragraphs that is causing the corresponding acronym not being found. ```

``` Funny, I've just run into the similar problem wanting to have chemical symbol (that shouldn't be all caps) in the title of a chapter.

You can try using "\NoCaseChange{\ac{UML}}" and "pdfspacing" (or "minionpro", if available) option of ClassicThesis.sty. The latter is needed so that letterspacing is not done by the package soul.sty as it has some problems with command calls inside its arguments. /look at the code in % * Fancy Stuff */ The problem might remain in the headings, though. I don't think it can be removed before \RequirePackage{titlesec} gets the option "explicit" and all the \titleformat's get redefined (by giving them lower and upper case titles explicitly as an argument). André will know better... and will probably first object on using \ac hyperlinks in the titles

``` Ivo, thanks a lot for your suggestions.

Unfortunately, I do not know better so far. The option "explicit" sounds interesting. However, as Ivo anticipated ;-), I suggest not to use such commands in the titles, i.e., you are likely to have only a few (1, 2?) occurrences of such cases and on the other hand, you are very unlikely to introduce an acronym within a title. :-\ ```
