When using the search engine in 'memory mode', CQP cannot access corpora with paths composed of accented or special characters.

A) Document the problem: See (FR) https://groupes.renater.fr/wiki/txm-users/public/faq#sous_windows_txm_07_et_versions_ulterieures_aucune_requete_cql_ne_fonctionne_sur_aucun_corpus

B) Temporary Solution:

• under Windows, check if the corpus directory path obeys current CQP character constraints (accented or special characters)
• if not, ask the user to change the 'TXM User Home directory' preference to something compatible with the current CQP constraints
• corpus directory path must be checked at installation and when the 'TXM User Home directory' preference is changed
• TXM should not give the impression to the user that it works until the 'TXM User Home directory' complies with the current CQP constraints

C) Definitive Solution

Change CQP registry directory access code to comply with current operating systems pathnames constraints.

Solution¶

• Replace FileSystem IO functions with glib FileSystem IO functions (fopen -> g_fopen, etc.)
• change registry files encoding to UTF-8 : On Windows and Mac OS X the system encoding is no UTF-8 and these files contain the DATA path to the index files.

Validation test¶

In a Windows TXM session:

• if necessary, create an account with accented characters
• if necessary, install TXM
• run TXM (from C:/Program files/TXM/TXM.bat if installed with another user)
• when selecting the VOEUX corpus, the corpus size must be shown in TXM status bar.
