After updated to 2020 version that added support to Asian languages (include Thai), it look like Indesign force user (in my case Thai) to set language in Advanced Character Formats to Thai. After set the language Indesign also require me to use World-Ready Composer to set all tone marks in place.
.
Before the latest version, I always avoid to use World-Ready Composer because it combines a word to single object, not just locks tone mark and float vowel to character in the right position. By which it impossible to navigate with text tool to the position of text that I want to revise, even if I use right/left key to navigate. It mostly skips word by word, not only character by character. And when I delete a word or a character, some time it not only deletes backward but forward too. (I think because of when I delete character form a word Indesign instantly recognises new word and forces to delete that new word.) But After updated to 2020, I think, I anymore cannot avoid World-Ready Composer.
.
After I designed to use World-Ready Composer, I found one more bug. Because in many situations when I craft the spacing in layout (especially in Thai), I always use thin-space to separate character like “ๆ” form word before and after to make the space between them look good. But After I set to World-Ready I found that when thin-space (include other spacial white space like en or em) is in the back of the line the spaces in question act like normal character, so the last character of the line when use left justify do not snap to right frame border. The space still there like It becames one of character. So you can see the gap between the last character and the right frame border. (you can find this instance in attachment in file “space issue.”)
.
But the serious issue still there after the update. I, and all of my co-workers, found that everything about word wrapping in Thai language goes wrong after updated to 2020 version. This never happen in the former versions. I don't understand why this issue is happen. Even if I use Discretionary Line Break to help Indesign to wrap text properly. But It is not productive at all, because I had been forced to read text all over again and to insert Discretionary Line Break to every lines. (you can find this instance in attachment in file “wrap gone wrong.” In the high-light is the words that should be stick together.)
.
PS. while I wrote this issue report, my co-worker tried to migrate back form 2020 to 2019 and she found that when copy revised text back to 2019 it not the same character encoding. I advised her to try to place that text to TextEdit. It appears that some character is changed to something that is not unicode at all. That never happen in previous versions too. ((you can find this instance in attachment in file “text form 2020” and “text form 2020.” the text form 2020 at frist did in 2019 before migrate to 2020.)

The following words in cannot be reproduced in InDesign. It seems the glyph substitution is not working in about 1% of cases.

র‍্যানিবিজুমাব — Bengali
ମହତ୍ଵପୂର୍ଣ୍ଣ — Oriya
ସ୍ଵେଚ୍ଛାକୃତ — Oriya
କିମ୍ଵା — Oriya

It looks fine above, in any text editor, or in any Microsoft app, but does NOT look right in any Adobe app I tested, such as InDesign, Illustrator, Photoshop CC 2019 and 2020 of each.
I am applying the World-Ready Composers.
I have tried copy+pasting the text from Word and also tried the Place command in InDesign.
I've tested in both the English North America and English Arabic versions.
I've tried multiple fonts, as well. No change.
See attached for examples. Word doc shows as it should be. InDesign shows it wrong. I highlighted the glyphs that are wrong in InDesign as pink.
Thanks!

When importing a Word document that contains some indented paragraphs, the left indent being set to 5mm in Word (for example), once placed in InDesign, these 5mm indents typically show as 4.992mm. This would not neccesarily be a problem except that Find/Change in InDesign will not recognise an indent to 3 decimal places and therefore this cannot be located easily and fixed. This is proving to be a big problem in my workflow as I cannot automate the process of re-styling these paragraphs using InDesign Paragraph Styles with Find/Change. This bug occurs whatever measurement system is used, i.e. mm, inches, pts etc. Version of InDesign used: 14.0.3 although the same problem exists back to CS6 at least.

I keep encountering the same glitch in multiple documents where an edit to the text on one page forces a blank page (although running head and page number remain) on the following page, with the text re-flowing as expected on the page after that. For example, deleting an unwanted space is a frequent cause of this glitch. So far I've found 2 ways of making the text return to it's correct position and removing the blank:

1) place my cursor at the very end of the page before the unwanted blank and enter a space - this brings the text back onto the blank but doesn't actually add a space.
2) make a minor adjustment to the tracking/kerning of a single character on the page before the unwanted blank.

Linked to this, occasionally some of my footnotes have disappeared as well - to get them back I have to adjust the size of the text box slightly and then restore it to its original size.

Any help or ideas would be greatly appreciated!

Justify vertically text frame is not correct every time particularly in more than 2 columns text frame. Tried all options and found some time there are space in bottom of last line as in attached file.

Reproduced in the same in 2 or more columns text frames. This happens in:

1. If used heading span 2 or more or spall all.

2. Placed any text wrap graphics,

3. Used with or without "Skip by leading"

All the instances are same results, in some cases the space are more than the attached file, particularly if used "span all" for heading and place any "text wrapped" object

I'm using Indesign 14.0.3 in windows 7 environement.
