Readtable produces a 1x 1 table full of strange characters

I am loading tables from several large nonuniform .txt files delaminated with spaces. I'm using readtable and most of the tables get loaded without an issue but some files generate a 1x1 table full of stange characters. The code I'm using to load:
filename = 'filename.txt'
opts = detectImportOptions(filename);
opts = setvartype(opts,'char'); % or 'string'
Table = readtable(filename,opts);
I can't tell what is causing some files to be read like this.

If you provide a sample file that causes this issue you will be more likely to get a good answer. Use the paper clip icon in the INSERT section of the comment editor toolbar to attach it.

If some of the imported data looks strange, that means the setvartype option is not appropriate for the data to be imported. See these two examples:
filename = 'DATA_2_MIX.txt';
opts = detectImportOptions(filename);
opts = setvartype(opts,'double'); % 'single','char' or 'string'
Table = readtable(filename,opts)
filename = 'DATA_2_MIX.txt';
opts = detectImportOptions(filename);
opts = setvartype(opts,'char'); % 'single','char' or 'string'
Table = readtable(filename,opts)
