[jira] [Commented] (PDFBOX-5487) extra whitespaces when extracting Arabic text
[ https://issues.apache.org/jira/browse/PDFBOX-5487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17905762#comment-17905762 ]
Mohamed M NourElDin commented on PDFBOX-5487:
---------------------------------------------
Yes, that's exactly what I expected.
In addition to {*}Malpass-at-the-G7-Leaders-Summit-Media-Briefing-AR.pdf{*}, I tested the following four files:
# *artikel1_20_arab.pdf*
** The space between the two words "النظامية مفتوحاً" was removed. However, this did not affect extraction accuracy, as the _teh marbuta_ (ة) only appears at the end of a word and is never connected to the letter on its left.
# *FES-GGArabisch-p112.pdf*
** No changes were observed.
# *PDFBOX-679-toobig.pdf*
** No changes were observed.
# *RAND_PE122z1.arabic.pdf*
** One extra space was removed correctly ("مؤك د" becomes "مؤكد").
** Eleven other extra spaces were removed, but these changes neither improved nor harmed extraction accuracy.
