And there's your problem. Non ASCII characters in your library path.

Spurious "No such file or directory" error when library's path contains post-ASCII characters

### Describe the problem If a library is installed under a path that contains… Cyrillic characters, Arduino CLI is unable to discover it. Compilation of sketches with an `#include` directive for a header file of a valid library fails with a "`No such file or directory`" error. ### To reproduce ```text $ arduino-cli version arduino-cli.exe Version: git-snapshot Commit: 4b70e023 Date: 2023-01-31T03:19:27Z $ export ARDUINO_DIRECTORIES_USER="/tmp/arduino-cli-directories/мікроконтролер" $ arduino-cli lib install Arduino_JSON [...] $ mkdir /tmp/FooSketch $ printf "#include <Arduino_JSON.h>\nvoid setup() {}\nvoid loop() {}" > /tmp/FooSketch/FooSketch.ino $ arduino-cli compile --fqbn arduino:avr:uno /tmp/FooSketch/FooSketch.ino C:\Users\per\AppData\Local\Temp\FooSketch\FooSketch.ino:1:10: fatal error: Arduino_JSON.h: No such file or directory #include <Arduino_JSON.h> ^~~~~~~~~~~~~~~~ compilation terminated. Used library Version Path Arduino_JSON 0.2.0 C:\Users\per\AppData\Local\Temp\arduino-cli-directories\мікроконтролер\libraries\Arduino_JSON Used platform Version Path arduino:avr 1.8.6 C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6 Error during build: exit status 1 ``` ### Expected behavior Any path supported by the file system is also supported by the library discovery system ### Arduino CLI version #### Original report Arduino IDE 1.8.10 #### Last verified with 4b70e023 ### Operating system Windows ### Operating system version - 10 - 11 ### Additional context The issue is not specific to Cyrillic. For example, it also occurs with a folder named `文` or `Κώστας`. --- The fault only occurs on Windows. I am not able to reproduce it on Ubuntu 22.04 or macOS Ventura machines. --- After changing system's locale from English to Bulgarian (win1251) + restart, the compilation succeeded. Unfortunately this is not viable solution, because we have many computers (>150) and changing system locale requires admin privileges. My suggestion is that the IDE is not using the unicode version of the API when searching for libraries? --- This is more likely to occur for those using [Microsoft **Onedrive**](https://en.wikipedia.org/wiki/OneDrive) because the default location of the sketchbook is: ```text C:\Users\<username>\OneDrive\<localized "Documents">\Arduino ``` The `<localized "Documents">` in the path above is a placeholder the word "Documents" localized for the user's locale (e.g., `文档` or `Документы`) #### Additional reports - https://forum.arduino.cc/t/wemos-d1-mini-upload-problem/1084371 - https://forum.arduino.cc/t/no-such-file-or-directory-but-i-already-had-this-file/961118 - https://forum.arduino.cc/t/fatal-error-adafruit-neopixel-h-no-such-file-or-directory-but-i-have-it/1070069/15 - https://forum.arduino.cc/t/library-gives-error/1089633 - https://forum.arduino.cc/t/except-for-the-available-libraries-i-cant-use-other-libraries-even-though-i-have-downloaded-them/1092556 - https://forum.arduino.cc/t/compilation-error-due-to-library-hpp-file-not-being-detected/1127096 - https://forum.arduino.cc/t/which-arduino-nano-clone-i-have/1192347/11 - https://forum.arduino.cc/t/cannot-verify-the-arduino-code-because-the-installed-library-cannot-be-found/1215989 - https://forum.arduino.cc/t/10-fatal-error-onewire-h-no-such-file-or-directory/1223739 - https://forum.arduino.cc/t/unknown-error-for-arduino-1-8-19/1234260 - https://forum.arduino.cc/t/compilation-of-keypad-library-example-fails-key-h-no-such-file-or-directory/1241109 - https://forum.arduino.cc/t/mg135-library-please-answer/1254438 - https://forum.arduino.cc/t/i-keep-getting-library-compilation-error-despite-having-the-library/1255423 - https://forum.arduino.cc/t/no-such-file-or-directory/1255862/1 - https://forum.arduino.cc/t/no-such-file-or-directory/1255862/18 - https://forum.arduino.cc/t/arduino-ide-2-3-2-do-not-read-any-installed-library/1256849 - https://forum.arduino.cc/t/have-library-error-eventhough-installed/1258722 - https://forum.arduino.cc/t/arduino-ide-cannot-find-time-library-even-though-it-exists/1261462 - https://forum.arduino.cc/t/adafruit-bmp280-h-no-such-file-or-directory/1265651 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details
