> Problem with ligatures converting from PDF to HTML with Tika
> ------------------------------------------------------------
>                 Key: TIKA-2054
>                 URL: https://issues.apache.org/jira/browse/TIKA-2054
>             Project: Tika
>          Issue Type: Bug
>    Affects Versions: 1.11, 1.13
>            Reporter: Angela Onslow

> When converting certain PDFs from PDF to HTML I am having trouble with ligature characters
> I have tried using Apache Tika 1.11 and 1.13, converting on the command line using the
.jar and get the same results.
> If I use pdfbox-app-2.0.1.jar and 'ExtractText' with the icu4j-57_1.jar in the path and
I convert to text rather than HTML then I am able to at least preserve information about what
each ligature was originally, even if they are still represented as unprintable characters.

> I.e. if I run the following from the command line:
> java -jar pdfbox-app-1.8.12.jar ExtractText 'test.pdf' 'test.txt'
> Then the resulting test.txt when viewed in Sublime2 has "fi" represented as the  US (unit
separator character), "ff" represented as RS, "fl" represented as GS and "ffl" reperesented
as FS, which I could then replace with the appropriate characters.
> I was under the impression Tika uses icu4j, is there a way to get the same behaviour
I see with PDFBox with Tika when converting from PDF to HTML?
