Summary0003112: Accents on letters eat up characters
Description

When a film title contains accented letters, those letters count double. For example, if I have a 20-character title with an accented letter (near the beginning), the film title will be reduced to 13 characters instead of 14 in the DCP name.

The same applies to apostrophes. When there's an apostrophe in a title, it's removed from the DCP name, but it still counts as a character, thus reducing the DCP name to 13 characters instead of 14.
Also, though this may only apply to French, the word following an apostrophe should be capitalized in the DCP name. In French, the apostrophe simply elides the preceding word. For example, the film "L'ombre au tableau" (The Shadow on the Painting) is represented in DCP as "LOmbreAuTableaFTR". The film "T'as pas changé" (You Haven't Changed) is represented in DCP as "TAsPasChangeFTR". It would be practical if we could separate the film name in the DCP file name from the film name in the metadata. This would allow us to adjust the DCP file name while keeping the full film title in the metadata.

For the film title and all along the CPL/DCP name you need to refrain from using anything else than the English alphanumeric characters. Excluding accents, acute or grave, circumflexes, centiles, umlaut, diaeresis, punctuation like the apostrophe and (the less obvious) i with no puncture (dot), etc., etc. Same goes for languages that use additional characters, like the double s in German, and I can go on more than necessary to make a point.
It's not only the number of the characters that DCP-o-matic will allow you to use, it might as well mess up the Media Block of the cinema server at the cinemas. I know first hand what I am writing about. An "í" (you see the acute accent?) that passed by the DCP maker of Premiere Pro obliged me to stop, delete the DCP and reboot both the server and the projector (Integrated Media Block), in order to restore the system's ability to work.

The DCP folder name, and -if used- in the .mxf files is the one from the CPL (Composition Playlist) "ContentTitleText", and not the other way around.
In other words, the restrictions that govern the xml tag <ContentTitleText> are/may affect the file/folder names, that otherwise might be named in another fashion (by the UUID of the CPL/MXF, or even more randomly).
So, if by "metadata" you refer to the CPL values and the way a DCP appears on the cinema-server, unfortunately, we are restricted from having a value such as "T'as pas changé".

https://cinema-int.com/CNCN/index.html does not underline the problem in question.

In regards to having more than 14 characters for the title, you may do that on DCP-o-matic if you un-check the ISDCF compatibility and edit the pre-set name.
I do that once in a while, not for extra characters, but to alternate capital and minuscule letters etc. after I have set all other parameters on the name (like language, subtitles, etc. etc.)
That, though, doesn't solve the so called " Le Problème " on that link I gave you earlier.

While that automatic dropping of characters may make „maður“ ("man" in Icelandic) to become "maur", it is a failsafe I am glad is there.

Could it be that by "metadata" you mean something else that the CPL entries?
