Hello,<br>
<br>
Tamil is a script that requires "special characters" support in text
mode. When you open in Oxygen a document that contains such script
(with default options) you are prompted to Enable/Disable support
for bidirectional text and special characters. When this support is
enabled, the performance is affected significantly. Larger documents
incur a more significant performance penalty. By default <b>this
support is disabled for files larger than 300KB, but performance
can be acceptable for up to 800KB.</b>

Why is that the case?</blockquote>
To answer your question, if you have the default limit of 300k in
Oxygen and are editing a file that is larger, the "special
characters" support is disabled without notification. With the
support disabled, it is normal for the cursor positioning and
editing to be "off".<br>
If you want to have it enabled, go to Options > Preferences,
Editor > Open/Save and in the section "Support for Special
Characters" <b>configure the 'Disable special characters support
for documents larger than (characters)' limit to 800k</b>. If you
feel confident it will hold, you could clear the Disable box (so
that it never gets disabled), but be aware that the larger the
document, the more it will slow down, up to making it appear as
hanged. If you disable the limit, I would advise to at least set it
to "Prompt for each document", so you can disable it yourself when
it's not needed.<br>

Oxygen XML Editor is a Java application and at least for the text
mode it uses the support that Java implements for rendering texts
and managing cursor positions. When dealing with large file sizes
and special scripts, the Java implementation struggles to
efficiently handle the text rendering and cursor positioning due the
complexity and nuances of the script that is not handled natively.<br>
<br>
On the other hand, text editors like Notepad++, which are solely
built for handling text files, might perform better with large files
and complex scripts because they use native methods (OS support) to
render and manage cursor positions in the text.<br>

<br>
<br>
I have often wondered why the size limit so low for comfortably
editing files in text mode in scripts such as Tamil?
<br>
<br>
I am currently editing an ancient Portuguese-Tamil dictionary
<br>
and as soon as the file size reaches a certain size, I can no
longer trust the cursor position.
<br>
<br>
To give an example,
<br>
if I edit today in text mode a file containing the equivalent of
one page, which has a size of 23 kB, I can trust the position of
the cursor
<br>
on screen to show me where the next Tamil character will be
inserted.
<br>
<br>
HOWEVER, if I edit in text mode a file containing the equivalent
of 60 pages (which has a size of 693 kB), I can no longer trust
what I see and have to enter the Tamil text without paying
attention to the position of the cursor, which is far to the right
side of the actual insertion position.
<br>
<br>
Why is that the case?
<br>
<br>
Why is a text editor such as Notepad++ capable of doing what
oXygen cannot do, with respect to rendering text containing
complex scritps such as Tamil?
<br>
<br>
Am I doing something wrong?
<br>
<br>
I would like to know
<br>
<br>
Thanks for any solution provided

P.S. The problem does not occur in Author mode, but one does not
always want to define a .CSS
