Problem when using WP-ShowHide

 

※ Problem in quotation mark (QM),
– happened also here: https://tech.narpen.org/wordpress/plugins/display-list-of-page-or-child-page/
– root cause: texturize in MS Word & WordPresshttps://www.kadencewp.com/blog/apostrophes-and-quotation-marks/
– how to resolve: by using wpuntexturize plugin
– how to check QM unicode : Unicode Character Search (FileFormat.info)
the right QM: U+0022: Quotation Mark (neutral)
the wrong QM: U+201D: Right Double Quotation Mark

Quotation Mark (QM) always changes into 'unusable' Right Double QM

When using WP-ShowHide, a QM is needed to write the necessary code. However, somewhere in the WordPress formatting feature, my normal QM ( U+0022) always changes into RDQM Right Double QM (U+201D). While it looks almost the same to the human eyes, the code just doesn't work again.

It took time for me to finally found the root case.
This can be checked through this Unicode Character Search (FileFormat.info)
Just copy and paste the QM into the query field, then press the 'Search' button, to know what Unicode character it represents (i.e., U+0022 or U+201D).

Character Name Unicode Block Unicode Encoding (UTF-16 Hex) Remarks
" Quotation Mark
–> but if I Publish the article, this character automatically become 'Left Double QM'
Basic Latin U+0022 The wanted character!
Right Double Quotation Mark General Punctuation U+201D

Next adventure (if I have the time & energy):
1. Find when exactly the QM change
2. Find the workaround (e.g., find a way to save into the "code" feature, "plain text" etc)
