Are octal \303\251 and octal \351 the same graphic, simply depending on charset locale?

https://unix.stackexchange.com/questions/129216/utf-8-sequence-in-the-console

\303\251 is valid in

UTF-8 locales where \303\251 is é

and

iso-8859-1 or iso-8859-15 (the two common single byte per character charsets that are common in French speaking countries) where \303\251 is Ã©

Here is an example of the humongous trouble you can get into by being permissive with your filename character set and then moving your file hierarchy to somebody's cloud server!

Dieudonné

From https://www.ascii-code.com/ we get this row for those 8 bits:

233 351 E9 11101001 é é é Latin small letter e with acute

On Windows, it is it as should be, assuming ASCII8 !

From the folder showing as Dieudonné on Windows 10, I had on Site5 2 folders. Before adding my index.php, they showed as:

New: Dieudonn\303\251 = DieudonnÃ©/ Weird/bad (shows as empty under file manager) but full when browsed Usable!!

Older: Dieudonn\351 = Dieudonné/ What I wanted visually and Usable.

It looks like I got these backward!

Both of these were usable, as chrome showed them (no index.php)!!!!!!!

Unfortunately, I only had one folder by the time I added the index.php, so I don’t know what would have been shown then!

Summary Thesis:

		Example1	Example 2
Small number or 1 escaped bytes	Liked by Windows 10, my index.php. May be or become undeletable except by inode number.	\351 = Dieudonné/ (Chrome Directory)	America\222s (PuTTY)
2 or 3 escaped bytes	Liked by SourceForge, my index.php.	\303\251 = DieudonnÃ©/ (Chrome Directory)	America's (PuTTY)

Also, chrome will show these differently (including not 1 to 1 characters to bits) depending on whether my index.php is present in the relevant folder!

Contradicting the above, we have my own investigation into the filename word Dieudonné
