is it not recommended to not set filename in latin?

tatagi · 01-24-2023, 12:49 PM

for example,

I have one epub book and it has chapter names written in korean

like

chapter챕터1.xhtml
chapter챕터2.xhtml

etc

I opened it in calibre editor, compressed images, saved a copy of the book, changed its extension to zip and opened it.

and what a surprise, the korean alphabets in the file names are all broken.
like this - chapter▒╫╖í╡╡ ┴┴╛╞1.xhtml

is it a must to set all the filenames(images, texts, fonts , css etc) using only alphanumeric?

the name of epub file itself could use korean with no issue.

Safest to K.I.S.S a file name. ASCII.
Besides, inside the book, only the editors see those. Sec001...Sec099 works just the same. or as I prefer: I name (abbreviated) by the purpose:TOC, AboutA, For, Aft, Part, Ind. I add a suffix number (padded leading 0 as needed) if there are multiple members.

챕터 is 'chapter'

If I change a file name, within an epub, from start.xhtml to 챕터 1.xhtml then the calibre book editor issues the following warning message:

FTR: Sigil issues a similar message

If I click Yes to "Are you sure" the file name is changed, viz:

@tatagi - what language setting do you have for your OS, calibre, and the book - mine are all English

Are you on macOS?

You should avoid non-ASCII characters in internal filenames, as EPUB postulates a complex relationship of URLs and binary ZIP filenames, and many readers are not fully supporting those.

thank you guys. korean characters are obviously non-ascii so that makes sense why it doesn't work flawlessly. problem is it takes time to check all my epubs first to see if there's non-ascii file names ever used.
